Alan Gates commented on HIVE-12376:
-----------------------------------
The default min/max for server threads in the metastore is 200/1000. Given
that we don't want compaction to eat too many metastore resources it would seem
to make sense to set the limit as a percentage of the maximum (maybe 10%?).
> make hive.compactor.worker.threads use a thread pool, etc
