Zoltan Haindrich commented on HIVE-25672:
-----------------------------------------

I tried to reproduce this issue; at first metastore.compactor.initiator.on was 
disabled on my cluster for some reason; but after turning that on things 
started working correctly:
* a metastore with 52M of heap was able to cleanup 10K of records in no time
** and was OOM-ed for 100K
* a metastore with 966K rows in the COMPLETED_COMPACTIONS table
** removed 50773 rows multiple times - and was able to reduce the volume to 
below 100 in around a minute

I don't know if we have an issue here - as it seems like that most likely for 
some reason either the `AcidHouseKeeperService` is not running - or stopped 
running for some reason
