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

             Summary: LogCleaner assumes first dirty offset zero if there is no 
cleaner checkpoint
                 Key: KAFKA-1373
                 URL: https://issues.apache.org/jira/browse/KAFKA-1373
             Project: Kafka
          Issue Type: Bug
    Affects Versions: 0.8.1
            Reporter: Joel Koshy
            Assignee: Joel Koshy
             Fix For: 0.8.1.1


If you try enabling the compaction policy on a topic that already exists and if 
its first segment starts with anything other than zero you will see something 
like this:

java.lang.IllegalArgumentException: requirement failed: Last clean offset is 0 
but segment base offset is 2722629 for log test-0.
