> 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.
