Migrating from 1.4.0 to 1.5.0
AWS components for NiFi have been reorganized into sub-projects nifi-aws-serice-api, nifi-aws-abstract-processors, and nifi-aws-processors to separate service interfaces from concrete implementation classes. Custom AWS components should be rebuilt to target NiFi 1.5.0. For bundles that only implement controller service interfaces (AWSCredentialsProviderService), it is recommended that the NAR dependency be changed to nifi-aws-service-api-nar. Custom AWS components built for earlier versions of NiFi can continue to be used if the matching version of the nifi-aws-nar.
- Migrating from 1.3.0 to 1.4.0
A restricted implementation of the SSLContextService has been added, StandardRestrictedSSLContextService. It provides the ability to configure keystore and/or truststore properties once and reuse that configuration throughout the application, but only allows a restricted ("modern") set of TLS/SSL protocols to be chosen (as of 1.4.0, no SSL protocols are supported, only TLS v1.2). The set of protocols selectable will evolve over time as new protocols emerge and older protocols are deprecated. The generic "TLS" entry is also supported and will automatically select the best available option without user intervention (this is the recommended setting). This service is recommended over StandardSSLContextService if a component doesn't expect to communicate with legacy systems since it is unlikely that legacy systems will support these protocols.
- The following Listen* processors now require a StandardRestrictedSSLContextService (previously requiring StandardSSLContextService): ListenBeats, ListenHTTP, ListenLumberjack, ListenRELP, ListenSMTP, ListenSyslog, ListenTCP, ListenTCPRecord
- ListenGRPC is a new processor for 1.4.0, and requires StandardRestrictedSSLContextService
- Dataflow managers will need to instantiate a new instance of StandardRestrictedSSLContextService and associate it with any of the above components in an existing flow
