-------------------------------------
Hi [~lianetm]
I would like to investigate this issue. :)
> 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
> Priority: Major
> Labels: consumer-threading-refactor, kip-848-client-support
> 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).
