Evgeny Ryabitskiy commented on HBASE-1480:
------------------------------------------
Same problem can be with split dir.
Not sure about master as an only entity to del dirs in HDFS. Region deletes its
compaction dir every time it starts compaction and after successfully finishes
it (2 times).
Master is a good place, I will also look if new HRS that got Region can do this
clean up.
> compaction file not cleaned up after a crash/OOME server

> We do not clean up compaction files after a crash/OOME of a region server.
> I am not sure how the compaction file naming is anymore if its not

> older then 24 hours in the compaction dir's of the tables
