ASF GitHub Bot commented on KAFKA-5474:
---------------------------------------

GitHub user mjsax opened a pull request:

    https://github.com/apache/kafka/pull/3375

    KAFKA-5474: Streams StandbyTask should no checkpoint on commit if EOS is enabled

     - actual fix for `StandbyTask#commit()`
    Additionally (for debugging):
     - EOS test, does not report "expected" value correctly
     - `StreamThread` does not report "standby tasks" correctly
     - add `IntegerDecoder` (to be use with `kafka.tools.DumpLogSegments`)
