             Summary: Error in processing fetched data for one partition may stop follower fetching other partitions
                 Key: KAFKA-7150
                 URL: https://issues.apache.org/jira/browse/KAFKA-7150
             Project: Kafka
          Issue Type: Bug
          Components: replication
    Affects Versions: 1.1.0, 1.0.2, 0.11.0.3, 0.10.2.2
            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.
