Subject [jira] [Created] (HBASE-15027) Refactor the way the CompactedHFileDischarger threads are created

----------------------------------------------

             Summary: Refactor the way the CompactedHFileDischarger threads are created
                 Key: HBASE-15027
                 URL: https://issues.apache.org/jira/browse/HBASE-15027
             Project: HBase
          Issue Type: Bug
            Reporter: ramkrishna.s.vasudevan
            Assignee: ramkrishna.s.vasudevan
             Fix For: 2.0.0


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.
