nifi.provenance.repository.indexed.fields. 10 secs). ProxyPass directive with the If you stored flows to an external location, update the property value to point there. The following tables summarize the global and component policies assigned to each legacy role if the NiFi instance has an existing flow.json.gz: For details on the individual policies in the table, see Access Policies. For example: nifi.provenance.repository.directory.provenance1= Data is sent to the target peer. The name of each property must be unique, for example: "User Group Provider A", "User Group Provider B", "User Group Provider C" or "User Group Provider 1", "User Group Provider 2", "User Group Provider 3". A comma separated list of allowed HTTP X-ProxyContextPath, X-Forwarded-Context, or X-Forwarded-Prefix header values to consider. The space-separated list of application protocols supported when running with HTTPS enabled. When connecting to another node in the cluster, specifies how long this node should wait before considering CN=Users,DC=example,DC=com). If not set, all Spring Vault authentication properties must be configured directly in bootstrap-hashicorp-vault.conf. In NiFi, this is accomplished by adding the following line to the $NIFI_HOME/conf/bootstrap.conf file: This will cause the debug output to be written to the NiFi Bootstrap log file. This property is only used when there are no other users, groups, and policies defined. In addition to the properties above, dynamic properties can be added. By default, the nodes emit applied on a Znode. Whenever a connection is created, a developer selects one or more relationships between those processors. Download the latest version of Apache NiFi. in data remaining in the content repository for much longer, potentially leading to the content repository running out of disk space. The default value is ./conf/state-management.xml. configure the web server to WANT certificate base client authentication. It is blank by default. All of the properties defined above (see File System Content Repository Properties) still apply. The default value is ./conf/truststore.p12. For example, to provide two additional library locations, a user could also specify additional properties with keys of: In the Cluster Management dialog, select the "Delete" icon () for a Disconnected or Offloaded node. Providing three total locations, including nifi.provenance.repository.directory.default. Later, it was desired to be able to compress the data so that Click the Add icon (). This output can be rather verbose but provides extremely valuable information for troubleshooting Kerberos failures. Otherwise the model will not be used and predictions will not be available until a model is generated with a score that exceeds the threshold. This If you retained the default location for storing flows (/conf/), copy flow.json.gz from the existing to the new NiFi base install conf directory. Global access policies govern the following system level authorizations: Allows users to view/modify the controller including Management Controller Services, Reporting Tasks, Registry Clients, Parameter Providers and nodes in the cluster. In the NiFi binary distribution, the login-identity-providers.xml file comes with a provider with the identifier ldap-provider and a property called Manager Password: Similarly, the authorizers.xml file comes with a ldap-user-group-provider and a property also called Manager Password: If the Manager Password is desired to reference the same exact property (e.g., the same Secret in the HashiCorp Vault K/V provider) but still be distinguished from any other Manager Password property unrelated to LDAP, the following mapping could be added: This would cause both of the above to be assigned a context of "ldap/Manager Password" instead of "default/Manager Password". In this case, client requests should be routed directly to a node without going through the reverse proxy. The Connect String that is needed to connect to Apache ZooKeeper. The default value is 8. nifi.flowfile.repository.rocksdb.max.write.buffer.number. However, the This is a comma-separated list Boolean value, true or false. The default value is 30 days. See Property Encryption Algorithms for supported values. nifi.cluster.flow.election.max.candidates - Specifies the number of Nodes required in the cluster to cause early election of Flows. (memberof=cn=team1,ou=groups,o=nifi)). File ManagerThe file-manager tool enables administrators to backup, install or restore a NiFi installation from backup. A complete example of configuring the HTTP service could look like the following: When running Apache NiFi behind a proxy there are a couple of key items to be aware of during deployment. suffers. The following examples demonstrate normalizing DNs from certificates and principals from Kerberos: The last segment of each property is an identifier used to associate the pattern with the replacement value. The ShellUserGroupProvider has the following properties: Duration of initial delay before first user and group refresh. The value of this property could be a DN (when using certificates or LDAP) or a Kerberos principal. Kerberos password associated with the principal. Here is the sample provided in the file: The ldap-provider has the following properties: How the connection to the LDAP server is authenticated. However, if it does not exist, NiFi will fall back to this I.e., the feature is disabled by as well as the issuer and expiration from the configured Login Identity Provider. The Java Runtime Environment provides the ability to specify custom TLS cipher suites to be used by servers when accepting client connections. nifi.zookeeper.connect.string - The Connect String that is needed to connect to Apache ZooKeeper. See RockDB ColumnFamilyOptions.setWriteBufferSize() / write_buffer_size for more information. With v0.5.0, additional KDFs are introduced with variable iteration counts, work factors, and salt formats. Defaults to false. nifi flow controller tls configuration is invalid. Access to Parameter Contexts are inherited from the "access the controller" policies unless overridden. For example, to provide two additional locations to act as part of the content repository, a user could also specify additional properties with keys of: nifi.content.repository.archive.backpressure.percentage. nifi.nar.library.provider.nifi-registry.implementation. In a clustered environment, all nodes must be be added to these policies as well, as a user request could be replicated through any node in the cluster. The ID of the Cluster State Provider to use. Group Membership - Enforce Case Sensitivity. Absence of this property value disables repository encryption. The full path to an existing authorized-users.xml that will be automatically converted to the new authorizations model. The discovery URL for the desired OpenId Connect Provider (http://openid.net/specs/openid-connect-discovery-1_0.html). After updating the above properties and starting NiFi, network communication with ZooKeeper will be secure and ZooKeeper will now use the NiFi nodes certificate principal Frequency at which to force a sync to disk. For information on securing the embedded ZooKeeper Server, see the Securing ZooKeeper with Kerberos section below. call the Provider to obtain the user identity. Password-Based Key Derivation Function 2 is an adaptive derivation function which uses an internal pseudorandom function (PRF) and iterates it many times over a password and salt (at least 16 bytes). /nifi-api/access/saml/single-logout/request. For production feature exists, it is also very common to simply use a standalone NiFi instance to pull data and feed it to the cluster. See Configuring State Providers for more information. This will stop all processors, terminate all processors, stop transmitting on all remote process groups and rebalance flowfiles to the other connected nodes in the cluster. further properties. be specified per NiFi instance, so this property is configured here to support SPNEGO and service principals rather than in individual Processors. This could potentially lead to the wrong attributes or content being assigned to a FlowFile upon restart, following the power loss or OS crash. Isolated Processors: In a NiFi cluster, the same dataflow runs on all the nodes. 1 min). Without The default is 1 GB and the value must be a data size including the unit of measure. When clustered, a property for each node should be defined, so that every node knows about every other node. PersistentProvenanceRepository may not be able to read the data written by the WriteAheadProvenanceRepository. This allows for the recovery of a system that is encountering OutOfMemory errors or similar on startup. Providing three total network interfaces, including nifi.web.http.network.interface.default. It will be of the form Authorization: Negotiate YII. The file where the FileAuthorizer stores users and groups. The Docker site makes it seem simple, but I appear to be getting huge exceptions and the contanier just stops after about 45 seconds. If the node is disconnected and unreachable, the offload request can not be received by the node to start the offloading. will use the same ZooKeeper instance, that the value of the Root Node property be changed. older versions of NiFi, upon startup, NiFi will use the nifi.flow.configuration.json.file first. Supported providers include: KEYSTORE. There are currently three implementations: StaticKeyProvider which reads a key directly from nifi.properties, FileBasedKeyProvider which reads keys from an encrypted file, and KeyStoreKeyProvider which reads keys from a standard java.security.KeyStore. When implemented, identities authenticated by different identity providers (certificates, LDAP, Kerberos) are treated the same internally in NiFi. NiFi supports several configuration options to provide authenticated encryption with associated data (AEAD) using AES Galois/Counter Mode (AES-GCM). If the number of Nodes that have voted is equal to the number specified by the nifi.cluster.flow.election.max.candidates nifi.flowfile.repository.rocksdb.sync.warning.period. Configuring repository encryption properties overrides the following repository implementation class properties, as well By clustering the NiFi servers, its possible to If archiving is enabled (see nifi.content.repository.archive.enabled below), then By default, it is blank, but the system administrator should provide a value for it. During the diagnostics command execution, the NiFi bootstrap process sends a request to the running NiFi instance, which collects information about the JVM, the operating system and hardware, the NARs loaded in NiFi, the flow configuration and the components being used, the long-running processor tasks, the clustering status, garbage collection, memory pool peak usage, NiFi repositories, parts of the NiFi configuration, a thread dump, etc., and writes it to the specified location. connect to the node using this hostname/IP address. Once all Provenance Events in the index have been aged off from the "event files," the index To increase the allowable number, edit /etc/security/limits.conf, And your distribution may require an edit to /etc/security/limits.d/90-nproc.conf by adding. For example: nifi.content.repository.directory.content1= nifi flow controller tls configuration is invalid. several seconds. Indicates whether to compress the provenance information when an "event file" is rolled over. For each Node, the minimum properties to configure are as follows: Under the Web Properties section, set either the HTTP or HTTPS port that you want the Node to run on. Also, if clients to reverse proxy uses HTTPS, reverse proxy server certificate should have wildcard common name or SAN to be accessed by different host names. The salt format is $s0$e0101$ABCDEFGHIJKLMNOPQRSTUV. The Content Repository implementation. + This is done so that the flow can be manually reverted if necessary Another available implementation is org.apache.nifi.wali.EncryptedSequentialAccessWriteAheadLog. When NiFi communicates with ZooKeeper, all communications, by default, are non-secure, and anyone who logs into ZooKeeper is able to view and manipulate all In this example, the users and groups are loaded from LDAP but the servers are managed in a local file. If you have retained the default value (./conf/flow.json.gz), copy flow.json.gz from the existing to the new NiFi base install conf directory. That is T+_. This property accepts a comma separated list of expected values. Must be PKCS12 or JKS or BCFKS. The default includes m=65536,t=5,p=8 - the cost parameters. The default value is org.apache.nifi.wali.SequentialAccessWriteAheadLog. nifi.nar.library.directory.lib1=/nars/lib1 The other two scenarios are when the request is proxied. for the expiration configured in the Login Identity Provider without persisting the private key. Encryption protocol Each NAR provider property follows the format nifi.nar.library.provider.. and each provider must have at least one property named implementation. The example1 routing does not match this for this request, and port 8081 is returned. To do so, set the value of this property to org.wali.MinimalLockingWriteAheadLog. Heartbeats: The nodes communicate their health and status to the currently elected Cluster Coordinator via "heartbeats", If not blank, this property will define the attribute of the group ldap entry that the value of the attribute defined in User Group Name Attribute is referencing (i.e. for some amount of time. If the configuration properties are not specified in bootstrap-aws.conf, then the provider will attempt to use the AWS default credentials provider, which checks standard environment variables and system properties. To avoid this situation, configure these repositories on different drives. Setting this true increases throughput if loss of data is acceptable. The default value is false. The location of the node firewall file. retrieving protected properties. RFC 5952 Sections 4 and 6 for additional details. It does not matter which order the instances start up. Indicates whether to compress the provenance information when rolling it over. The FileAuthorizer has the following properties: The file where the FileAuthorizer stores policies. nifi.provenance.repository.max.attribute.length. The default value is 5 mins. NiFi PutFile processor doesn't save file to a directory 4 Apache NiFi Unable to start the flow controller because the TLS configuration was invalid: The keystore properties are not valid If not set, the entire DN is used. These properties must be configured in order for NiFi (i.e. Generated JSON Web Tokens include the authenticated user identity has yet been elected the "correct" flow, the nodes flow is compared to each of the other Nodes' flows. Logging for deprecated Enabling this feature allows the system to protect itself by restricting (delaying or denying) operations that increase the total FlowFile count on the node to prevent the system from being overwhelmed. settings, or refactoring custom component classes. properties can be specified. This also means that if a standalone instance Many other Security Properties must also be configured. In order to facilitate the secure setup of NiFi, you can use the encrypt-config command line utility to encrypt raw configuration values that NiFi decrypts in memory on startup. It just depends on the resources available and how the Administrator decides to configure the cluster. The default value is ./diagnostics. The CompositeConfigurableUserGroupProvider has the following properties: The default AccessPolicyProvider is the FileAccessPolicyProvider, however, you can develop additional AccessPolicyProvider as extensions. Specifies the amount of time to wait before electing a Flow as the "correct" Flow. The Initial Admin Identity value came from an attribute in a LDAP entry based on the User Identity Attribute. Depending on the capabilities of the configured UserGroupProvider and AccessPolicyProvider the users, groups, and policies will be configurable in the UI. With 'Server name to Node', the same port can be used to route requests to different upstream NiFi nodes based on the requested server name (e.g. not be voted to be the "correct" flow unless no other flow is found. The name of the scoring type that should be used to evaluate the model. The nifi.cluster.flow.election.max.wait.time property determines how long NiFi waits before deciding on a flow. If the configuration properties are not specified in bootstrap-aws.conf, then the provider will attempt to use the AWS default credentials provider, which checks standard environment variables and system properties. Refer to the following examples for actual configurations. Configuring State Providers section for more information). NiFi can only be configured for username/password, OpenId Connect, or Apache Knox at a given time. In the event of a failure (e.g. NiFi will at any one time potentially have a very large number of file handles open. The default value is false. can begin proxying user requests. The implementation class for the status analytics model used to make connection predictions. Managed Identity (i.e. configured recipients whenever NiFi is stopped. 5 mins). It is also advisable, if multiple NiFi instances describes the process for credentials resolution, which leverages environment variables, system properties, and falls This version of the write-ahead log was added in version 1.6.0 of Apache NiFi and was developed that should be used for storing data. NiFi supports user authentication via client certificates, via username/password, via Apache Knox, or via OpenId Connect. Specifies the fully qualified java command to run. These properties apply to the core framework as a whole. Antivirus software can take a long time to scan large directories and the numerous files within them. one-instance cluster, or if communications with ZooKeeper occur only over encrypted communications, such as a VPN or an SSL connection. Cipher suites that may not be used by an SSL client to establish a connection to Jetty. The default is one hour: PT1H. When there is no more data to send, or reached to batch limit, the transaction is confirmed on both end by calculating CRC32 hash of sent data. This property is a comma-separated list of Notification Service identifiers that correspond to the Notification Services As a result, this property defaults to a value of 0, indicating that the metrics should be captured 0% of the time. (i.e. Requests in excess of this are rejected with HTTP 429. The default value is: %{client}a - %u %t "%r" %s %O "%{Referer}i" "%{User-Agent}i". Use these sections as advice, but The full path and name of the truststore. The default value is 8443. Requires Single Logout to be enabled. The salt length is determined based on the selected algorithms cipher block length. The default value is 30 sec. in the $NIFI_HOME/conf/nifi.properties file: Whether to acccess ZooKeeper using client TLS. the user can create/modify all restricted components. here. Whether the Server header should be included in HTTP responses. This property specifies the maximum permitted size of the diagnostics directory. NiFi uses JSON Web Tokens to provide authenticated access after the initial login process. running ZooKeeper on 4 nodes provides no more benefit than running on 3 nodes, ZooKeeper requires a majority of nodes be active in order to function. There are three If predictions are needed sooner than what is provided by default, the timing of snapshots can be adjusted using the nifi.components.status.snapshot.frequency value in nifi.properties. The EncryptContent processor allows for the encryption and decryption of data, both internal to NiFi and integrated with external systems, such as openssl and other data sources and consumers. How many threads to use on startup restoring the FlowFile state. This runs NiFi in the foreground and waits for a Ctrl-C to initiate shutdown of NiFi, To see the current status of NiFi, double-click status-nifi.bat. in order to address an issue that exists in the older implementation. If set to true, client certificates are not required to connect via TLS. format, and repository implementation classes. This section assumes the users, groups, and policies are configurable in the UI and describes: How access policies are used to define authorizations, How to view policies that are set on a user, How to configure access policies by walking through specific examples. Provenance Events as they are generated and providing the ability to iterate over those events sequentially. JKS is the preferred type, BCFKS and PKCS12 files will be loaded with BouncyCastle provider. is used approximately 10% of the time (500 / 5,000 * 100%). If archiving is enabled (see nifi.content.repository.archive.enabled below), then this property must have a value that indicates the content repository disk usage percentage at which archived data begins to be removed. When an authenticated user attempts to view or modify a NiFi resource, the system checks whether the The configuration file format expects one entry per line and ignores lines beginning with the # character. of the property that the State Provider supports. Type of the Keystore that is used when connecting to LDAP using LDAPS or START_TLS (i.e. users, groups, and policies will read-only in the UI. authentication. Filters available ciphers if set. FEATURED TAGS. The encryption algorithm used is specified by nifi.sensitive.props.algorithm and the password from which the encryption key is derived is specified by nifi.sensitive.props.key in nifi.properties (see Security Configuration for additional information). If Kerberos is not already setup in your environment, you can find information on installing and setting up a Kerberos Server at This is the fully-qualified class name of the key provider. Once the nifi.security.autoreload.enabled property is set to true, any valid changes to the configured keystore and truststore will cause NiFis SSL context factory to be reloaded, allowing clients to pick up the changes. This can result in lower NiFi performance. The instructions below are general steps to follow when upgrading from a 1.x.0 release to another. On decryption, the salt is read in and combined with the password to derive the encryption key and IV. Attempting to access a clustered node through a gateway without session affinity will result in intermittent failures of The default value is 65536. If not specified, will default to the value used by the The default value is 5000. from the remote node before considering the communication with the node a failure. The configuration for the client side of the connection will operate in the same way as an external ZooKeeper. Your existing NiFi may have multiple content repos defined. Repository encryption configuration uses a version number to indicate the cipher algorithms, metadata Paths set using these options are relative to the NiFi Home Directory. This is a file that may be used to list all the nodes that are allowed to connect This can be used with a traditional HDFS instance or with cloud storage, such as s3a or abfs. The default value is Integer.MAX_VALUE, nifi.provenance.repository.directory.default*. The fully qualified class name of the implementation class which is org.apache.nifi.registry.extension.NiFiRegistryNarProvider. That way all context See Encrypted Content Repository in the User Guide for more information. Currently NiFi supports HDFS based providers. It can be set to the identifier from a provider in the file specified in nifi.login.identity.provider.configuration.file. This If it is not possible to install the unlimited strength jurisdiction policies, the Allow Weak Crypto setting can be changed to allowed, but this is not recommended. log errors to that effect and will fail to startup. This KDF performs no operation on the input and is a marker to indicate the raw key is provided to the cipher. NiFi is comprised of a number of web applications (web UI, web API, documentation, custom UIs, data viewers, etc), so the mapping needs to be configured for the root path. The default value is org.apache.nifi.controller.repository.WriteAheadFlowFileRepository. The default value is 25. nifi.content.repository.directory.content1=/repos/content1 If it is desired that the HTTPS interface be accessible from all network interfaces, a value of 0.0.0.0 should be used. To enable content archiving, set this to true and specify a value for the nifi.content.repository.archive.max.usage.percentage property above. Example $NIFI_HOME/conf/zookeeper.properties file: When used with a three node NiFi cluster, the above configuration file would establish a three node ZooKeeper quorum with each node listening on secure port 2281 for client connections with NiFi, 2888 for quorum communication and 3888 for leader election. IPv6 addresses are accepted. where filesystem encryption is not configured, repository encryption provides an enhanced level of data protection. A comma separate listed of allowed audiences. In the Property file we can also specify the keystore and truststore file paths in case we have secured NiFi instances using SSL/TLS, but this is beyond the scope of this article. The name of the HTTP Cookie that Apache Knox will generate after successful login. A good value is the number of cores. nifi.provenance.repository.directory.default=. Users from the configurable user group provider are configurable, however users loaded from one of the User Group Provider [unique key] will not be. By default the full principal is used however setting the kerberos.removeHostFromPrincipal and the kerberos.removeRealmFromPrincipal properties to true will instruct Therefore, once the Provenance Repository is changed to use Optional. nifi.nar.library.provider.nifi-registry.url. The default value is org.apache.nifi.provenance.WriteAheadProvenanceRepository. The sticky directive As a result, if we set the value of this property higher, up to a value of 100, we will get more accurate results. If not blank, this property will define the attribute of the user ldap entry that the value of the attribute defined in Group Member Attribute is referencing (i.e. The salt format is $argon2id$v=19$m=65536,t=5,p=8$ABCDEFGHIJKLMNOPQRSTUV. Additional NiFi proxy configuration must be updated to allow expected Host and context paths HTTP headers. available again. The expiration duration of a successful Kerberos user authentication, if used. one of the ZooKeeper servers, we will accomplish this by performing the following commands: For the next NiFi Node that will run ZooKeeper, we can accomplish this by performing the following commands: For more information on the properties used to administer ZooKeeper, see the However, this can be tuned depending on the CPU resources available compared to the I/O resources. If the limit is exceeded, the oldest files are deleted. The default value is single-user-provider. If necessary the krb5 file can support multiple realms. However, there are many environments in which NiFi is deployed where there is no existing ZooKeeper ensemble being maintained. Running the following Encrypt-Config command would read in the flow.xml.gz and nifi.properties files from 1.9.2 using the original sensitive properties key and write out new versions in 1.10.0 with the sensitive properties encrypted with the new password: -f specifies the source flow.json.gz (nifi-1.9.2), -g specifies the destination flow.json.gz (nifi-1.10.0), -s specifies the new sensitive properties key (new_password), -n specifies the source nifi.properties (nifi-1.9.2), -o specifies the destination nifi.properties (nifi-1.10.0), -x tells Encrypt-Config to only process the sensitive properties. This provider uses AWS Secrets Manager Service to store and retrieve AWS Secrets. The default value is 25. This can be found in the Azure portal under Azure Active Directory App registrations [application name] Directory (tenant) ID. When NiFi is started, this root key is used to decrypt sensitive values from the nifi.properties file into memory for later use. This is configured by specifying an XML file that defines which notification services can be used. For deployments they must be set the same on every instance in the cluster. nifi.security.user.oidc.truststore.strategy. There is an alternate implementation, EncryptedFileSystemSwapManager, that encrypts the swap file content on Policy inheritance enables an administrator to assign policies at one time and have the policies apply throughout the entire dataflow. By default, archiving is enabled. To add and configure a new processor, follow these steps: From . These parameters should be increased to the threshold at which legitimate systems will encounter detrimental delays (use Argon2SecureHasherTest#testDefaultCostParamsShouldBeSufficient() to calculate safe minimums). at org.apache.nifi.controller.FlowController.<init>(FlowController.java:501) .
