Summary: retrying to close a region incorrectly resets its RIT age metric Key: HBASE-21757 URL: https://issues.apache.org/jira/browse/HBASE-21757 Project: HBase Issue Type: Bug Affects Versions: 3.0.0 Reporter: Sergey Shelukhin We have a region stuck in RIT forever due to some other bug that I will file later. Every 10 minutes it does the typical split-brain retry; I noticed that this retry resets the region's RIT age, so the "oldest RIT" metric never becomes larger than ~10mins even though the region has been stuck for days. {noformat} 2019-01-22 10:40:52,993 INFO [PEWorker-10] assignment.RegionStateStore: pid=1865 updating hbase:meta row=region, regionState=CLOSING, regionLocation=server,17020,1547824687684 2019-01-22 10:40:53,025 WARN [PEWorker-10] assignment.RegionRemoteProcedureBase: Can not add remote operation pid=29297, ppid=1865, state=RUNNABLE, hasLock=true; org.apache.hadoop.hbase.master.assignment.CloseRegionProcedure for region {ENCODED => region, ...} to server server,17020,1547824687684, this usually because the server is alread dead, give up and mark the procedure as complete, the parent procedure will take care of this. 2019-01-22 10:40:53,040 INFO [PEWorker-10] procedure2.ProcedureExecutor: Finished subprocedure(s) of pid=1865, state=RUNNABLE:REGION_STATE_TRANSITION_CONFIRM_CLOSED, hasLock=true; TransitRegionStateProcedure table=table, region=region, REOPEN/MOVE; resume parent processing. 2019-01-22 10:40:53,040 WARN [PEWorker-7] assignment.TransitRegionStateProcedure: Failed transition, suspend 600secs pid=1865, state=RUNNABLE:REGION_STATE_TRANSITION_CLOSE, hasLock=true; TransitRegionStateProcedure table=table, region=region, REOPEN/MOVE; rit=CLOSING, location=server,17020,1547824687684; waiting on rectified condition fixed by other Procedure or operator intervention 2019-01-22 10:40:53,040 INFO [PEWorker-7] procedure2.TimeoutExecutorThread: ADDED pid=1865, state=WAITING_TIMEOUT:REGION_STATE_TRANSITION_CLOSE, hasLock=true; TransitRegionStateProcedure table=table, region=region, REOPEN/MOVE; timeout=600000, timestamp=1548183053040 {noformat} !image-2019-01-22-11-00-39-030.png! -- This message was sent by Atlassian JIRA (v7.6.3#76005)
