[jira] [Created] (KAFKA-20330) Share partition leader restart without leadership change gives wrong exception

Andrew Schofield created KAFKA-20330:
----------------------------------------

             Summary: Share partition leader restart without leadership change gives wrong exception
                 Key: KAFKA-20330
                 URL: https://issues.apache.org/jira/browse/KAFKA-20330
             Project: Kafka
          Issue Type: Bug
    Affects Versions: 4.2.0
            Reporter: Andrew Schofield
            Assignee: Andrew Schofield
             Fix For: 4.3.0


If I have a single-broker cluster and a share consumer with implicit acknowledgement, it is possible to get a share session error when records are fetched before the broker restarts but acknowledged afterwards. The handling of the exception looks good, but it's not the intended exception in this situation. The code handles leadership change correctly, but it can be confused by a leadership non-change in spite of a restart.
