             Summary: New consumer should notify HB errors to group manager after errors have been handled/propagated
                 Key: KAFKA-18017
                 URL: https://issues.apache.org/jira/browse/KAFKA-18017
             Project: Kafka
          Issue Type: Bug
          Components: consumer
    Affects Versions: 3.9.0, 3.9.1
            Reporter: Lianet Magrans
            Assignee: Lianet Magrans
             Fix For: 4.0.0


Ensure that the heartbeat manager notifies the group manager about errors only after those errors have been handled and propagated. This is important to ensure that there is an ErrorEvent propagated to the app thread when the group manager takes actions on failures, like completing an ongoing unsubscribe (app thread should be aware of the error before the unsubscribe completes).

Consider the fix for cases then the HB receives a response containing an error code, and also for then the HB request fails (ie. network failures).
