[jira] [Created] (KAFKA-1629) Replica fetcher thread need to back off upon getting errors on partitions

Guozhang Wang created KAFKA-1629:
------------------------------------

             Summary: 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
             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.
