---------------------------------------
> Enhance Compaction Cleaner to skip when there is nothing to do
> --------------------------------------------------------------
>
> Key: HIVE-25883
> URL: https://issues.apache.org/jira/browse/HIVE-25883
> Project: Hive
> Issue Type: Bug
> Reporter: Zoltan Haindrich
> Assignee: Zoltan Haindrich
> Priority: Major
>
> the cleaner works the following way:
> * it identifies obsolete directories (delta dirs ; which doesn't have open
> txns)
> * removes them and done
> if there are no obsolete directoris that is attributed to that there might be
> open txns so the request should be retried later.
> however if for some reason the directory was already cleaned - similarily it
> has no obsolete directories; and thus the request is retried for forever
