-------------------------------------

             Summary: ProducerFencedException is not Handled on Offest Commit
                 Key: KAFKA-10631
                 URL: https://issues.apache.org/jira/browse/KAFKA-10631
             Project: Kafka
          Issue Type: Bug
          Components: clients
    Affects Versions: 2.7.0
            Reporter: Bruno Cadonna


The transaction manager does currently not handle producer fenced errors 
returned from a offset commit request.

We found this bug because we saw the following exception in our soak cluster:

{code:java}
org.apache.kafka.streams.errors.StreamsException: Error encountered trying to 
commit a transaction [stream-thread [i-037c09b3c48522d8d-StreamThread-3] task
