             Summary: Replica fetcher should not update partition state on diverging epoch if partition removed from fetcher
                 Key: KAFKA-13207
                 URL: https://issues.apache.org/jira/browse/KAFKA-13207
             Project: Kafka
          Issue Type: New Feature
          Components: core
    Affects Versions: 2.8.0
            Reporter: Rajini Sivaram
            Assignee: Rajini Sivaram
             Fix For: 3.0.0, 2.8.1


{{AbstractFetcherThread#truncateOnFetchResponse}}{color:#24292e} is used with IBP 2.7 and above to truncate partitions based on diverging epoch returned in fetch responses. Truncation should only be performed for partitions that are still owned by the fetcher and this check should be done while holding {color}{{partitionMapLock}}{color:#24292e} to ensure that any partitions removed from the fetcher thread are not truncated{color}
