-----------------------------------
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.
