Resolution: Duplicate
> Replica fetcher thread need to back off upon getting errors on partitions
> -------------------------------------------------------------------------
>
> Key: KAFKA-1629
> URL: https://issues.apache.org/jira/browse/KAFKA-1629
> Project: Kafka
> Issue Type: Bug
> Reporter: Guozhang Wang
> Labels: newbie++
> Fix For: 0.9.0
>
>
> ReplicaFetcherThread's handlePartitionsWithErrors() function needs to be
> implemented (currently it is an empty function) such that upon getting errors
> on these partitions, the fetcher thread will back off the corresponding
> simple consumer to retry fetching that partition.
> This can happen when there is leader migration, the replica may get a bit
> delayed receiving the leader ISR update request before keeping retry fetching
> the old leader.
