Chandra Sekhar K updated HBASE-29154:
-------------------------------------
Description:
There are some random exceptions when HRegion.closeRegionOperation is being
executed.
This is causing the Region Scanner opened in RSRpcService.java not getting
closed resulting in the corresponding HFile opened by the scanner not getting
cleaned up by the CompactedHFilesDischargeHandler due to the File RefCount not
zero.
