Boyang Chen reassigned KAFKA-9535:
----------------------------------
Assignee: Boyang Chen
> Metadata not updated when consumer encounters FENCED_LEADER_EPOCH
> -----------------------------------------------------------------
>
> Key: KAFKA-9535
> URL: https://issues.apache.org/jira/browse/KAFKA-9535
> Project: Kafka
> Issue Type: Bug
> Affects Versions: 2.3.0, 2.4.0, 2.5.0
> Reporter: Boyang Chen
> Assignee: Boyang Chen
> Priority: Major
>
> Inside the consumer Fetcher's handling of ListOffsetResponse, if we hit
> `FENCED_LEADER_EPOCH` on partition level, the client will blindly retry
> without refreshing the metadata, creating a stuck state as the local leader
> epoch never gets updated and constantly fails the broker check.
> The solution is to trigger metadata update upon receiving retriable errors,
> before we kick off another offset list.
