             Summary: Broker should not set leader epoch if the list-offset request version < 4
                 Key: KAFKA-10613
                 URL: https://issues.apache.org/jira/browse/KAFKA-10613
             Project: Kafka
          Issue Type: Improvement
          Components: streams
            Reporter: Guozhang Wang
            Assignee: Guozhang Wang


The list-offset response added a new field in version 4:

{code}
        { "name": "LeaderEpoch", "type": "int32", "versions": "4+" }
{code}

And the compiled code would throw UnsupportedVersionException if that field is not default (-1) with version < 4. However, on the broker side we forget to add the logic to not setting this field based on the request version. This would cause old versioned clients' list-offset call to always get UnsupportedVersionException and an empty result would be returned.
