CFM 2.1.4

CFM 2.1.4 is based on Apache NiFi 1.16.0 and includes significant improvements and fixes. The most important new features and improvements of the release are:

The flow.xml.gz file replaced with flow.json.gz
CFM 2.1.4 NiFi started using a flow.json.gz instead of the flow.xml.gz file used in all previous versions. On startup, NiFi converts the existing flow.xml.gz to a flow.json.gz file. If a flow.json.gz already exists, NiFi ignores the flow.xml.gz on startup. Changes made on the canvas will currently be written to both the new flow.json.gz version as well as the flow.xml.gz file; however, only the flow.json.gz is loaded on NiFi startup.
Supported NiFi Registry databases changed
Following some security related changes and dependency upgrades, the list of supported databases for the NiFi Registry component has been updated. Make sure you are using a supported version before upgrading to CFM 2.1.4. For more information, see Supported NiFi Registry databases.
Kafka 0.x processors removed

Some Elasticsearch processors removed
Elasticsearch processors that were leveraging the Elasticsearch 2.0 library and the deprecated Transport Client have been removed. It means that the below processors are no longer provided and supported by Cloudera. It is recommended to switch to the processors interacting with Elasticsearch over HTTP.
  • FetchElasticsearch
  • PutElasticsearch
For more information, see Supported NiFi processors.
Retry at framework level
This feature provides the ability to define a retry strategy for the flowfiles going into a given relationship for each processor.
Clustering model and flow definition reconciliation
A disconnected node in a NiFi cluster will no longer cause the UI to be read-only for flow changes and a reconciliation will be executed on the flow definition when the node rejoins the cluster.
Snowflake Connection Pool controller service
This controller service can be used in combination with the JDBC processors to easily interact with Snowflake for both pulling and pushing data.
Query Salesforce Object processor
A new processor is available that can be used to ingest data from Salesforce with incremental changes.
OAuth 2 integration with InvokeHTTP processor
It is now possible to configure an OAuth2 token provider with InvokeHTTP to easily interact with services requiring OAuth2 authentication.
