-------------------------------------
Hey Jay. I checked it again. You are right, I missed that deleted suffix. There
are some other theories I got, but I'll close this ticket for now and open
another one after I verify it. Thanks.
> LogCleaner delete file asynchronously and can cause inconsistency between log
> cleaner checkpoint and first dirty log segment file.

> In LogCleaner we delete the log segment file asynchronously and then
> checkpoint the cleaned offsets. If broker exit after checkpoint is written
> but before log segment got deleted, when the broker start again, it will have
> the first dirty log offset different from the check-pointed offset.
