> 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.
