NiFi depends on Apache ZooKeeper for determining which node in the cluster should play the role of Primary Node ZooKeeper uses the Java Authentication and Authorization Service (JAAS), so we need to create a JAAS-compatible file In the $NIFI_HOME/conf/ directory, create a file (From NiFi 1.15.3, secure cluster is created without user has to manually enter these values and create certs for the same using nifi-toolkit or via organisation). But some good examples to consider are filename and mime.type as well as any custom attributes you might use which are valuable for your use case. See UserGroupProviders) will look for previous configurations to restore from. What this means is that NiFi has dependencies on ZooKeeper in order to If unspecified, the runtime SSLContext defaults are used. The location of the flow configuration file (i.e., the file that contains what is currently displayed on the NiFi graph). When a Lucene index is opened for the first time, it can be very expensive and take Example: /etc/krb5.conf, The name of the NiFi Kerberos service principal, if used. Optional. Enabling an alternative authentication mechanism will Apache NiFiSSL/TLS . Windows users will need to ensure "Microsoft Visual C++ 2015 Redistributable" is installed for this repository to work. NOTE: Multiple network interfaces can be specified by using the nifi.web.https.network.interface. When a component has no work to do (i.e., is "bored"), this is the amount of time it will wait before checking to see if it has new data to work on. nifi.properties. The default value is true. The framework then fetches new NAR files and copies them to (memberof=cn=team1,ou=groups,o=nifi)). The default location of the XML file is conf/bootstrap-notification-services.xml, but this value can be changed in the conf/bootstrap.conf file. The space-separated list of application protocols supported when running with HTTPS enabled. used. Three additional repositories are available as well. Optional. Another important file is conf/nifi.properties. member). With the proper dataflow configuration, it could pull in data and load-balance it across the rest of the nodes in the cluster. The default value is ./work/jetty. An optional Kerberos password for authentication. This means that multiple sources/implementations can be configured and composed. For each instance, certain properties in the nifi.properties file will need to be updated. This A thread pool is used for replicating requests to all nodes. For example, if a user is given access to view and modify a process group, that user can also view and modify the components in the process group. of the NiFi state that is stored in ZooKeeper. It should be noted that if Processors and other components save state using the Clustered scope, the Local State Provider will be used nifi.cluster.node.protocol.port - Set this to an open port that is higher than 1024 (anything lower requires root). Writes will be refused until the archive delete process has brought the content repository disk usage percentage below nifi.content.repository.archive.max.usage.percentage. Will rely on group membership being defined through Group Member Attribute if set. To store provenance events in memory instead of on disk (in which case all events will be lost on restart, and events will be evicted in a first-in-first-out order), name). Additionally, lets consider or methods will not generate deprecation logs. These properties govern how that process occurs. In this case, the graceful.shutdown.seconds property should be set to a higher value in the bootstrap.conf configuration file. For this reason, flow administrators should confirm that the Specifies the buffer size for the Status History Repository. 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. Users can determine which node is currently elected as the Primary Node by The queue threshold at which NiFi starts to swap FlowFile information to disk. When creating the replacement policy, you are given a choice to override with a copy of the inherited policy or an empty policy. When a The default value should be used and should not be changed. Kyber and Dilithium explained to primary school students? All HTTP requests from a single client must be routed to the same Apache NiFi node for the duration of an authenticated The default value is 99.9%. The default value is 40. nifi.flowfile.repository.rocksdb.delayed.write.bytes.per.second. See RockDB DBOptions.setIncreaseParallelism() for more information. The default value is ./content_repository. Comprehensive instructions for Kerberos server configuration and administration are beyond the scope of this document (see MIT Kerberos Admin Guide), but an example is below: Adding a service principal for a server at nifi.nifi.apache.org and exporting the keytab from the KDC: NiFi has an internal analytics framework which can be enabled to predict back pressure occurrence, given the configured settings for threshold on a queue. This means that using a username and password should not be used unless ZooKeeper is running on localhost as a The AzureGraphUserGroupProvider has the following properties: Duration of delay between each user and group refresh. request is authenticated or rejected. Also, consider whether you need to set the HTTP or HTTPS host property. From there, they will resume their path through the flow as normal. See the NiFi Toolkit Guide for an example. Sets whether group membership decisions are case sensitive. Boolean value, true or false. and can be viewed in the Cluster page. When using Kerberos, it is import to use fully-qualified domain names and not use localhost. This KDF is not memory-hard (can be parallelized massively with commodity hardware) but is still recommended as sufficient by NIST SP 800-132 (PDF) and many cryptographers (when used with a proper iteration count and HMAC cryptographic hash function). In order to maintain backward compatibility of flows and still load flows developed using The number of days the node status data (such as Repository disk space free, garbage collection information, etc.) How can we cool a computer connected on top of or within a human brain? Generated JSON Web Tokens include the authenticated user identity The password for the certificate in the Keystore. Base DN for searching for users (i.e. authentication. In order to run securely, the following properties must be set: Filename of the Keystore that contains the servers private key. A utility method is available at ScryptCipherProvider#translateSalt() which will convert the external form to the internal form. But if that user wants to start The optional storage location, such as hdfs://hdfs-location. For deployments The keystore.jks and truststore.jks files are both in the conf folder. In v0.4.0, another method of deriving the key, OpenSSL PKCS#5 v1.5 EVP_BytesToKey was added for compatibility with content encrypted outside of NiFi using the openssl command-line tool. A key provider is the datastore interface for accessing the encryption key to protect the provenance events. proxy. This limits the number of FlowFiles loaded into the graph at a time, while not actually removing any FlowFiles (or content) from the system. The krb5.conf file on the systems with the embedded zookeeper servers should be identical to the one on the system where the krb5kdc service is running. with any Authorizers that support this. It is blank by default. 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. Troubleshooting Guide may be of value. Below is an example and description of configuring a Login Identity Provider that integrates with a Kerberos Key Distribution Center (KDC) to authenticate users. supports different strategies, including cookie and route options. Must be PKCS12, JKS, or PEM. Providing three total network interfaces, including nifi.web.https.network.interface.default. appropriate access to shared Znodes in ZooKeeper. An extensive explanation can be found here. nifi.flowfile.repository.rocksdb.max.background.flushes. Please refer to Specifies whether NiFi creates a backup copy of the flow automatically when the flow is updated. The client secret for NiFi after registration with the OpenId Connect Provider. Warning: You may experience data loss if content repositories are not accessible to the new NiFi. A comma separate listed of allowed audiences. The first section of the nifi.properties file is for the Core Properties. Thats okay, just add to the file). I am trying to start NiFi 1.14.1 with TLS and LDAP and am running into problems all the way. Specify whether the remote peer should be accessed via secure protocol. Apache NiFiProcessorsController Services; CATALOG. that only the user that will be running NiFi is allowed to read this file. The number of journal files that should be used to serialize Provenance Event data. In order to transfer data via Site-to-Site protocol through reverse proxies, both proxy and Site-to-Site client NiFi users need to have following policies, 'retrieve site-to-site details', 'receive data via site-to-site' for input ports, and 'send data via site-to-site' for output ports. Requests in excess of this are rejected with HTTP 429. Repository encryption supports access to secret keys using standard java.security.KeyStore files. The default value is 65536. nifi.provenance.repository.concurrent.merge.threads. The Swap Manager implementation. These algorithms use a strong Key Derivation Function to derive a secret key of specified length based on the sensitive properties key configured. The modify the component policy that currently exists on the processor (child) is the modify the component policy inherited from the root process group (parent) on which User1 has privileges. It will result in data loss in the event of power/machine failure or a restart of NiFi. How long to wait when connecting to ZooKeeper before considering the connection a failure. This may happen for a few reasons, for example when the node is unable to communicate with the Cluster Coordinator due to network problems. nifi.nar.library.directory.lib1=/nars/lib1 This should contain a list of all ZooKeeper This indicates whether communication between this instance of NiFi and remote NiFi instances should be secure (i.e., secure site-to-site). Group names can also be mapped. However, one can still choose to opt into I.e., the feature is disabled by When an authenticated user attempts to view or modify a NiFi resource, the system checks whether the Matches against the group displayName to retrieve only groups with names ending with the provided suffix. nifi.flowfile.repository.encryption.key.provider.implementation. Disabling repository encryption on existing installations requires removing existing repository contents, and The AzureGraphUserGroupProvider fetches users and groups from Azure Active Directory (AAD) using the Microsoft Graph API. The default value is: EventType, FlowFileUUID, Filename, ProcessorID. See RocksDB DBOptions.setMaxBackgroundFlushes() / max_background_flushes for more information. The Key Provider implementation that repository implementations will use for retrieving keys necessary for encryption and decryption. However, it is worth noting that just because a node is disconnected does not mean that it is not working. The type of the Truststore. If you have retained the default location (./state/local), copy the complete directory tree to the new NiFi. I've looked at the start script to see what is being done and set the different environment variables to go through the proper sections in the file. It is recommended to install the JCE Unlimited Strength Jurisdiction Policy files for the JVM to mitigate this issue. But some good examples to consider are filename, uuid, and mime.type as well as any custom attritubes you might use which are valuable for your use case. consisting of 32 characters and stored using bcrypt hashing. Refer to that comment for usage examples. To enable and configure TLS manually for NiFi, edit the security properties according to the cluster configuration. Additionally, it allows for Configuring this property would allow requests where the proxy path is contained in this listing. The nifi.properties file in the conf directory is the main configuration file for controlling how NiFi runs. NiFi can be configured to use Kerberos SPNEGO (or "Kerberos Service") for authentication. The entity id of the service provider (i.e. nifi.flowfile.repository.rocksdb.enable.recovery.mode. components may indicate which specific permissions are required. Specifies the Email address to use as the sender. Set this to true if the instance is a node in a cluster. tasks to manage which nodes are allowed in the cluster and providing the most up-to-date flow to newly joining nodes. The path to the Apache Knox public key that will be used to verify the signatures of the authentication tokens in the HTTP Cookie. *Unsalted key derivation is a security risk and is not recommended. The name of a group containing NiFi cluster nodes. The provider supports the following KeyStore Types: The keystore filename extension must be either .p12 indicating PKCS12 or .bcfks indicating BCFKS. The key must be provided in hexadecimal encoding and be of a valid length for the associated cipher/algorithm. Any node whose dataflow, users, groups, and policies conflict with those elected will backup any conflicting resources and replace the local This property is optional, but if populated the groups will be passed along to the authorization process. is an XML file where the notification capabilities are configured. NiFi keeps FlowFile information in memory (the JVM) NiFis web server will REQUIRE certificate based client authentication for users accessing the User Interface when not configured with an alternative Instead, ensure that the new NiFi is pointing to the same files. This is important to set correctly, as which cluster properties. configuring the Key Provider implementation as well as the Key Identifier that will be used for new encryption Use the existing NiFi bootstrap-notification-services.xml file to update properties in the new NiFi. The primary (nifi, in this case) is the identifier that will be used to identify the user when authenticating Configuring State Providers section for more information). happen automatically. This specifies the ZooKeeper properties file to use. and for the partition(s) of interest, add the noatime option. Allow NiFi to run until there is no active data in any of the queues in the dataflow(s). Some browsers (legacy IE) do not support recent encryption algorithms such as AES, and are restricted to legacy algorithms (DES). Duration of delay between each user and group refresh. It can be set to the identifier from a provider in the file specified in nifi.login.identity.provider.configuration.file. nifi.flowfile.repository.rocksdb.sync.warning.period. throughput environments, where more CPU and disk I/O is available, it may make sense to increase this value significantly. The maximum number of level-0 files. The Azure Identity client library When NiFi is instructed to shutdown, the Bootstrap will wait this number of seconds for the process to shutdown cleanly. Enabling session affinity requires different settings depending on the product or service providing access. From this, NiFi will calculate that the CPU Username/password authentication is performed by a 'Login Identity Provider'. Here are some example reverse proxy and NiFi setups to illustrate what configuration files look like. This should not be enabled unless necessary to recover a system, and should be disabled as soon as that has been accomplished. If you retained the default location for storing flows (
