> Project: Hive
> Issue Type: Sub-task
> Components: Transactions
> Reporter: Eugene Koifman
> Priority: Major
>
> Deletion of aborted deltas happens from CompactorMR.run() i.e. from Worker
> but the Worker still sets compaction_queue entry to READY_FOR_CLEANING.
> This is not needed if there are no base_N dirs which can be created by Insert Overwrite
> In this case we can't delete deltas < N until we know no one is reading them, i.e. in Cleaner
