Anoop Sam John commented on HBASE-15027:
----------------------------------------
{code}
public static final String HBASE_HSTORE_COMPACTION_DISCHARGER_THREAD_COUNT =
68 "hbase.hstore.compaction.discharger.thread.count";
{code}
This name make sense now? As it is not at store level
{code}
CompactedHFilesDischargeHandler handler = new CompactedHFilesDischargeHandler(
100 (Server) ((HRegion)
region).getRegionServerServices(),
101 EventType.RS_COMPACTED_FILES_DISCHARGER, (HStore)
store);
102 ((HRegion)
region).getRegionServerServices().getExecutorService().submit(handler);
{code}
U have the RS ref in this class. No need to get from region right?

> As per suggestion given over in HBASE-14970, if we need to create a single
> thread pool service for the CompactionHFileDischarger we need to create an
> exectuor service in the RegionServer level and create discharger handler
> threads (Event handlers) and pass the Event to the new Exectuor service that
> we create for the compaction hfiles discharger. What should be the default
> number of threads here? If a HRS holds 100 of regions - will 10 threads be
> enough? This issue will try to resolve this with tests and discussions and
> suitable patch will be updated in HBASE-14970 for branch-1 once this is
> committed.
