Stamatis Zampetakis commented on HIVE-25115:
--------------------------------------------
Hey [~dkuzmenko] , [~klcopp] , can someone please clarify what does the phrase
"queue entry is thrown back to the queue" mean?
I am looking into the code and it seems that we are not adding something new in
the queue. My understanding is that when the cleaner does not delete any files
then we are leaving the compaction entry in the queue and this can create
problems.
> Compaction queue entries may accumulate in "ready for cleaning" state

> If the Cleaner does not delete any files, the compaction queue entry is
> thrown back to the queue and remains in "ready for cleaning" state.
> Problem: If 2 compactions run on the same table and enter "ready for
> cleaning" state at the same time, only one "cleaning" will remove obsolete
> files, the other entry will remain in the queue in "ready for cleaning" state.
