-------------------------------------
Summary: [Kinesis][EFO] EAGER registration strategy does not work
when job fails over
Key: FLINK-24431
URL: https://issues.apache.org/jira/browse/FLINK-24431
Project: Flink
Issue Type: Bug
Components: Connectors / Kinesis
Affects Versions: 1.13.2, 1.12.5, 1.14.0
Reporter: Danny Cranmer
Fix For: 1.12.6, 1.13.3, 1.15.0, 1.14.1
*Background*
The EFO Kinesis connector will register and de-register stream consumers based
on the configured [registration
strategy|https://ci.apache.org/projects/flink/flink-docs-release-1.13/docs/connectors/datastream/kinesis/#efo-stream-consumer-registrationderegistration].
When {{EAGER}} is used, the client (usually job manager) will register the
consumer and then the task managers will de-register the consumer when job
stops/fails. If the job is configured to restart on fail, then the consumer
will not exist and the job will continuously fail over.
*Solution*
The proposal is to not deregister the stream consumer when {{EAGER}} is used.
The documentation should be updated to reflect this.
