--------------------------------------
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).
