ramkrishna.s.vasudevan updated HBASE-14970:
-------------------------------------------
Release Note:
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.
