In the $NIFI_HOME/conf/ directory, create a file named zookeeper-jaas.conf and add to it the following snippet: We then need to tell NiFi to use this as our JAAS configuration. number of merge threads larger than this can result in all index threads being used to merge, which would cause the NiFi flow to periodically pause while indexing is happening, approach requires the presence of the standard metadata properties, but provides a compatibility layer that avoids nifi.provenance.repository.directory.default=. provide better performance. As a result, nifi0.example.com:10443, nifi1.example.com:10443 and nifi2.example.com:10443 are returned. To learn more, see our tips on writing great answers. Additionally, when a new node elects to join the cluster, the new node must first 10 secs). NiFi uses generated RSA Key Pairs with a key size of 4096 bits to support the PS512 algorithm for JSON Web Signatures. To prevent these performance and reliability issues from occurring, it is highly recommended to configure your antivirus software to skip scans on the following NiFi directories: NiFi uses logback as the runtime logging implementation. Clustered installations of NiFi require the same value to be configured on all nodes. This opens the NiFi Users dialog. The FileAccessPolicyProvider has the following properties: The identifier for an User Group Provider defined above that will be used to access users and groups for use in the managed access policies. 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). (i) I have tried creating keystores and truststores using the following two . This can be accomplished by setting the nifi.state.management.embedded.zookeeper.start property in nifi.properties to true on those nodes By default NAR files will be downloaded if no file with the same name exists in the folder defined by nifi.nar.library.autoload.directory. The location of the persistent Status History Repository. Point the new NiFi at the same external provenance repository location. Offloaded nodes can be either reconnected to the cluster (by selecting Connect or restarting NiFi on the node) or deleted from the cluster. Supported KeyStore types include: PKCS12 and BCFKS. the connection a failure. Group membership will be driven through the member attribute of each group. The limited write rate to the DB if slowdown is triggered. Server Configuration. + Because of US export regulations, default JVMs have limits imposed on the strength of cryptographic operations available to them. It is typically recommended that this property be set to 4-8 times the number of nodes in your cluster. Find or enter User2 and select OK. By adding User2 to the modify the component policy on the process group, User2 is added to the modify the component policy on the LogAttribute processor by policy inheritance. mechanisms for accomplishing this. If this property is missing, empty, or 0, a random ephemeral port is used. The system is unable to do this automatically because in a new flow the UUID of the root process group is not permanent until the flow.json.gz is generated. When the DFM makes changes to the dataflow, the node that receives the request to change the flow communicates those changes to all The default value is 30 sec. In order to edit a component, a user must be on both the view the component and modify the component policies. The default value is false. nifi flow controller tls configuration is invalid. Setting the level attribute to The default value is false. for some amount of time. This indicates that the service provider (i.e. The default value is ./conf/state-management.xml. If set the storage location defined in the core-site.xml will be overwritten by this value. If the Client has already been configured to use Kerberos, this is not necessary, as it was done above. USE_USERNAME will use the username the user logged in with. NIFI.APACHE.ORG). In order to override this behaviour, the nifi.nar.library.restrain.startup needs to be declared. mechanism that is used to store and retrieve this state is then determined based on this Scope, as well as the configured State NiFi). If no other Node has reported the same flow yet, this This KDF is recommended as it requires relatively large amounts of memory for each derivation, making it resistant to hardware brute-force attacks. The maximum size (HTTP Content-Length) for PUT and POST requests. the user can create/modify all restricted components. Possible values are USE_DN and USE_USERNAME. The EncryptedWriteAheadProvenanceRepository builds upon the WriteAheadProvenanceRepository and ensures that data is encrypted at rest. that is specified. For these KDFs, the output consists of the salt, followed by the salt delimiter, UTF-8 string NiFiSALT (0x4E 69 46 69 53 41 4C 54) and then the IV, followed by the IV delimiter, UTF-8 string NiFiIV (0x4E 69 46 69 49 56), followed by the cipher text. Enabling encryption and configuring a Key Provider using these properties applies to all repositories. A good value is the number of cores. 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. ./conf/archive/. This is actually the log2 value, so the total iteration count would be 210 (1024) in this case. annotations provide the ability to configure cookie attributes, including expiration. After we have created our Principal, we will need to create a KeyTab for the Principal: This keytab file can be copied to the other NiFi nodes with embedded zookeeper servers. Authorizers are configured using two properties in the nifi.properties file: The nifi.authorizer.configuration.file property specifies the configuration file where authorizers are defined. Maximum number of heartbeats a Cluster Coordinator can miss for a node in the cluster before the Cluster Coordinator updates the node status to Disconnected. file, rather than being configured via the nifi.properties file, simply because different implementations may require different properties, Initial User Identity - The identity of a users and systems to seed the Users File. The salt length is determined based on the selected algorithms cipher block length. The mapped context name if RegEx matches the identifier, otherwise default. nifi.flowfile.repository.rocksdb.accept.data.loss. If the repository implementation is configured to use the WriteAheadFlowFileRepository, this property can be used to specify which implementation of the This decodes to a 16 byte salt used in the key derivation. This provider executes various shell pipelines with commands such as getent on Linux and dscl on macOS. See Encrypted Content Repository in the User Guide for more information. Make sure the exact same property names are used and point to the appropriate matching provenance repo locations. 10 - the work factor. AWS KMS configuration properties can be stored in the bootstrap-aws.conf file, as referenced in bootstrap.conf. On a JVM with limited strength cryptography, some PBE algorithms limit the maximum password length to 7, and in this case it will not be possible to provide a "safe" password. Automatically created archives have filename with ISO 8601 format timestamp prefix followed by . 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 the future, we hope to provide supplemental documentation that covers the NiFi Cluster Architecture in depth. certificate avoids the verification issues associated with JSON Web Tokens, but is still subject to problems related to This required the capacity to encode arbitrary salts and Initialization Vectors (IV) into the cipher stream in order to be recovered by NiFi or a follow-on system to decrypt these messages. A NAR provider retrieves NARs from an external source and copies them to the directory specified by nifi.nar.library.autoload.directory. The default value is 1 min. On the other hand, Client2 has two URIs for Site-to-Site bootstrap URIs, and initiates the protocol using one of them. This implementation is capable of downloading files from an HDFS file system. nifi.repository.encryption.protocol.version. The CompositeUserGroupProvider will provide support for retrieving users and groups from multiple sources. The following table provides an example property name mapping: URI for the Azure Key Vault service such as https://{value-name}.vault.azure.net/, This protection scheme uses Google Cloud Key Management Service (Google Cloud Key Management Service) for encryption and decryption. This indicates that the identity provider should sign assertions, but some identity providers may provide their own configuration for controlling whether assertions are signed. The XML file that contains configuration for the local and cluster-wide State Providers. + from org.apache.nifi.provenance.PersistentProvenanceRepository to org.apache.nifi.provenance.WriteAheadProvenanceRepository. This ensures that even if the node has data stored in a connection, and the clusters dataflow is different, Generated JSON Web Tokens include the authenticated user identity to interested parties. NiFi offers a web-based User Interface for creating, monitoring, and controlling data flows. Each node in a clustered environment is configured with the same custom properties. Now, we must place our custom processor nar in the configured directory. A value of JDK indicates to use the JDKs default truststore. Client2 decides to use nifi2:8081 for further communication. If a NiFi cluster is planned to receive/transfer data from/to Site-to-Site clients over the internet or a company firewall, a reverse proxy server can be deployed in front of the NiFi cluster nodes as a gateway to route client requests to upstream NiFi nodes, to reduce number of servers and ports those have to be exposed. The full path and name of the keystore. The end user identity must be relayed in a HTTP header. * as described above. nifi.security.user.oidc.additional.scopes. The system stores RSA If not set group membership will not be calculated through the groups. Optional. The request timeout for web requests. The location of the krb5 file, if used. to this node, and this node is responsible for disconnecting nodes that do not report any heartbeat status Double check all configured properties for typos. m=65536,t=5,p=8 - the cost parameters. value of this property may increase the rate at which the Provenance Repository is able to process these records, resulting in better overall throughput. This KDF is recommended as it offers a variety of modes which can be tailored to prevention of GPU attacks, prevention of side-channel attacks, or a combination of both. + One of the nodes is automatically elected (via Apache The number of days the component status data (i.e., stats for each Processor, Connection, etc.) The following table lists the default ports used by NiFi and the corresponding property in the nifi.properties file. prefix with unique suffixes and separate paths as values. JSON Web Token support includes revocation on logout using JSON Web Token Identifiers. Similarly, nifi.remote.input.http. Disabled components with deprecated properties Fields that are not indexed will not be searchable. The value can be set to h2 http/1.1 to support Application Layer Protocol Negotiation (ALPN) for HTTP/2 or HTTP/1.1 based on client capabilities. provides less durability in the face of failure. IPv6 addresses are accepted. If not clustered, these properties can be ignored. However, it may be more expensive to monitor. some queries that are run often and the results are cached to avoid searching the Lucene indices). Below is an example graph of the linear regression model for Queue/Object Count over time which is used for predictions: In order to generate predictions, local status snapshot history is queried to obtain enough data to generate a model. An example Apache proxy configuration that sets the required properties may look like the following. nifi.flowfile.repository.rocksdb.enable.recovery.mode. Providing three total locations, including nifi.provenance.repository.directory.default. To use this implementation, set nifi.flowfile.repository.implementation to org.apache.nifi.controller.repository.VolatileFlowFileRepository. configured recipients if the bootstrap determines that NiFi has unexpectedly died. configured in the state-management.xml file. 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. standard logback.xml configuration with default appender and level settings. tasks to manage which nodes are allowed in the cluster and providing the most up-to-date flow to newly joining nodes. request is authenticated or rejected. separated list in nifi.properties using the nifi.web.proxy.host property (e.g. Here are the KDFs currently supported by NiFi (primarily in the EncryptContent processor for password-based encryption (PBE)) and relevant notes: The original KDF used by NiFi for internal key derivation for PBE, this is 1000 iterations of the MD5 digest over the concatenation of the password and 8 or 16 bytes of random salt (the salt length depends on the selected cipher block size). Larger values increase performance, especially during bulk loads. The default value is ./lib and probably should be left as is. For example, if nifi.content.repository.archive.max.usage.percentage is 50% and nifi.content.repository.archive.backpressure.percentage is not set, the effective value of nifi.content.repository.archive.backpressure.percentage will be 52%. Example: /etc/krb5.conf, The name of the NiFi Kerberos service principal, if used. Therefore, the amount of hardware and memory needed will depend on the size and nature of the dataflow involved. POSIX file permissions were recommended to limit unauthorized access to these files. 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. Optional. The location of the Jetty working directory. Specifies how long a transaction can stay alive on the server. The newer configuration files may introduce new properties that would be lost if you copy and paste configuration files. uid). Additionally, a single configurable user group provider is required. The default value is 10 secs. The remote input socket port for Site-to-Site communication. These algorithms use a strong Key Derivation Function to derive a secret key of specified length based on the sensitive properties key configured. The main components of . Configuring these properties correctly would require some understandings on Site-to-Site protocol sequence. Following This is intended to allow expired certificates to be updated in the keystore and new trusted certificates to be added in the truststore, all without having to restart the NiFi server. The reason that the Cluster Coordinator in the User Interface. The default value is: EventType, FlowFileUUID, Filename, ProcessorID. The Status History Repository implementation. Up to max_write_buffer_number write buffers may be held in memory at the same time, so you may wish to adjust this parameter to control memory usage. The name attribute must start with deprecation, followed by the component class. 528), Microsoft Azure joins Collectives on Stack Overflow. This is a comma-separated list of the fields that should be indexed and made searchable. Required if the Vault server is TLS-enabled, Keystore password. The default value is ./work/jetty. myHost2.example.com, or whatever fully qualified hostname the ZooKeeper server will be run on. The default authorizer is the StandardManagedAuthorizer. Instructions for enabling TLS on an external For example, to provide two additional locations to act as part of the provenance repository, a user could also specify additional properties with keys of: If you are also setting up a new external ZooKeeper, see the ZooKeeper Migrator section for instructions on how to move ZooKeeper information from one cluster to another and migrate ZooKeeper node ownership. For all three instances, the Cluster Common Properties can be left with the default settings. gather these metrics. If archiving is enabled (see nifi.content.repository.archive.enabled below), then The period at which to dump rocksdb.stats to the log. If left blank, it defaults to localhost. Attribute to use to define group membership (i.e. If the value of the property nifi.components.status.repository.implementation is VolatileComponentStatusRepository, the However, if it does not exist, NiFi will fall back to this Here is an example loading users and groups from LDAP. 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. Some reverse proxy technologies do not support server name routing rules, in such case, use 'Port number to Node' technique. The number of FlowFiles to load into the graph when in "recovery mode". Allows users to view/modify Parameter Contexts. authorization based on the requested resource. In order to run securely, the following properties must be set: Filename of the Keystore that contains the servers private key. Connect and share knowledge within a single location that is structured and easy to search. NOTE: This value should be at least 3 times greater than nifi.components.status.snapshot.frequency to ensure enough observations are retrieved for predictions. The heap usage at which to begin stalling writes to the repo. This allows NiFi to avoid constantly making HTTP requests to the remote system, which is particularly important when this instance of NiFi If NiFi is configured to run in a standalone mode, the cluster-provider element need not be populated in the state-management.xml This will create a file in the current directory named nifi.keytab. nifi.provenance.repository.indexed.attributes. The heap usage at which to begin stopping the creation of new FlowFiles. Filesystem encryption at the The connection timeout of the Vault client, A comma-separated list of the enabled TLS cipher suites, A comma-separated list of the enabled TLS protocols, Path to a keystore. One of the most important notes in the above Troubleshooting guide is the mechanism for turning on Debug output for Kerberos. As a result, this property defaults to a value of 0, indicating that the metrics should be captured 0% of the time. The first 8 or 16 bytes of the input are the salt. that can be converted to a byte array. Refer to the comment for a starter configuration. The comma separated list of properties in nifi.properties to encrypt in addition to the default sensitive properties (see Encrypted Passwords in Configuration Files). If this is the case, NiFi must also be configured with an Authorizer that supports authorizing an anonymous user. The NiFi node computes Site-to-Site port for RAW. After that, the ability to index and query the data was added. (i.e. The rest of the property name is not relevant, other than to differentiate property names, and will be ignored. The Docker site makes it seem simple, but I appear to be getting huge exceptions and the contanier just stops after about 45 seconds. The default values There are two types of requests-to-NiFi-node mapping techniques those can be applied at reverse proxy servers. Select the Override link in the policy inheritance message. Other values for this algorithm will attempt to parse as an RSA or EC algorithm to be used in conjunction with the will be kept. NiFi supports fetching NAR files for the autoloading feature from external sources. If the below properties point to directories inside the NiFi base installation path, you must copy the target directories to the new NiFi. nifi.security.user.login.identity.provider. I was running just fine before the upgrade. Browsers have varying levels of restriction when dealing with SPNEGO negotiations. The coordinator then replicates it to all nodes. The provider supports the following KeyStore Types: The keystore filename extension must be either .p12 indicating PKCS12 or .bcfks indicating BCFKS. As an example, if 4 requests are made, a 5 node cluster will use 4 * 7 = 28 threads. should run on. In an Apache NiFi data flow, flowfiles move from one to another processor through connection that gets validated using a relationship between processors. Required if searching users. The default value is 8443. Indicates the maximum length that a FlowFile attribute can be when retrieving a Provenance Event from the repository. org.apache.nifi.web.NiFiCoreException: Unable to start Flow Controller. Requests in excess of this are first delayed, then throttled. This KDF is provided for compatibility with data encrypted using OpenSSLs default PBE, known as EVP_BytesToKey. This is particularly important if your flow will be setting up and tearing Also, consider whether you need to set the HTTP or HTTPS host property. The arguments must include a reference to the BouncyCastle Security Provider library, which Paths set using these options are relative to the NiFi Home Directory. Overriding a policy removes the inherited policy, breaking the chain of inheritance from parent to child, and creates a replacement policy to add users as desired. resources with those from the cluster. more data could be stored. The second option for securely authenticating to and communicating with ZooKeeper is to use For information on securing the embedded ZooKeeper Server, see the Securing ZooKeeper with Kerberos section below.
