[jira] [Created] (KAFKA-15643) Improve unloading logging

David Jacot created KAFKA-15643:
-----------------------------------

             Summary: Improve unloading logging
                 Key: KAFKA-15643
                 URL: https://issues.apache.org/jira/browse/KAFKA-15643
             Project: Kafka
          Issue Type: Sub-task
            Reporter: David Jacot


When a new leader is elected for a __consumer_offset partition, the followers are notified to unload the state. However, only the former leader is aware of it. The remaining follower prints out the following error:
ERROR [GroupCoordinator id=1] Execution of UnloadCoordinator(tp=__consumer_offsets-1, epoch=0) failed due to This is not the correct coordinator.. (org.apache.kafka.coordinator.group.runtime.CoordinatorRuntime)
The error is actually correct but we should improve the logging to not print anything when in the remaining follower case.
