      After this JIRA we will not be doing any scanner reset after compaction during a course of a scan. The files that were compacted will still be continued to be used in the scan process. The compacted files will be archived by a background thread that runs every 2 mins by default only when there are no active scanners on those comapcted files.

      'hbase.hfile.compaction.discharger.interval' describes the interval after which the compaction discharger chore service should run.
      The property 'hbase.hfile.compaction.discharger.thread.count' describes the thread count that does the compaction discharge work.

      The CompactedHFilesDischarger is a chore service now started as part of the RegionServer and this chore service iterates over all the onlineRegions in that RS and uses the RegionServer's executor service to launch a set of threads that does this job of compaction files clean up.
