             Summary: Error in processing fetched data for one partition may 
stop follower fetching other partitions
                 Key: KAFKA-7150
             Project: Kafka
          Issue Type: Bug
          Components: replication
    Affects Versions: 1.1.0, 1.0.2,,
            Reporter: Anna Povzner

If the followers fails to process data for one topic partitions, like out of 
order offsets error, the whole ReplicaFetcherThread is killed, which also stops 
fetching for other topic partitions serviced by this fetcher thread. This may 
result in un-necessary under-replicated partitions. I think it would be better 
to continue fetching for other topic partitions, and just remove the partition 
with an error from the responsibility of the fetcher thread.
