[jira] [Created] (KAFKA-9656) TxnOffsetCommit should not return COORDINATOR_LOADING error for old request versions

Jason Gustafson created KAFKA-9656:
--------------------------------------

             Summary: TxnOffsetCommit should not return COORDINATOR_LOADING error for old request versions
                 Key: KAFKA-9656
                 URL: https://issues.apache.org/jira/browse/KAFKA-9656
             Project: Kafka
          Issue Type: Bug
            Reporter: Jason Gustafson


In KAFKA-7296, we fixed a bug which causes the producer to enter a fatal state when the COORDINATOR_LOADING_IN_PROGRESS error is received. The impact of this bug in streams was that the application would crash. Generally we want users to upgrade to a later client version, but in some cases, this takes a long time. I am suggesting here that we revert this behavior for older versions of TxnOffsetCommit. For versions older than 2 (which was introduced in 2.3), rather than returning COORDINATOR_LOADING_IN_PROGRESS, we can return COORDINATOR_NOT_AVAILABLE.
