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

             Summary: LogCleaner (compaction) does not support compressed topics
                 Key: KAFKA-1374
                 URL: https://issues.apache.org/jira/browse/KAFKA-1374
             Project: Kafka
          Issue Type: Bug
            Reporter: Joel Koshy
             Fix For: 0.8.2


This is a known issue, but opening a ticket to track.

If you try to compact a topic that has compressed messages you will run into
various exceptions - typically because during iteration we advance the
position based on the decompressed size of the message. I have a bunch of
stack traces, but it should be straightforward to reproduce.
