      Description

      Encountered this recently: the log cleaner exited a while ago (I think because the topic had compressed messages). That issue was subsequently addressed by having the producer only send uncompressed. However, on a subsequent restart of the broker we see this:

      In this scenario I think it is reasonable to just emit a warning and have the cleaner round up its first dirty offset to the base offset of the first segment.

      [kafka-server] [] [kafka-log-cleaner-thread-0], Error due to 
      java.lang.IllegalArgumentException: requirement failed: Last clean offset is 54770438 but segment base offset is 382844024 for log testtopic-0.
