Subject [jira] Created: (HBASE-2482) regions in transition do not get reassigned by master when RS crashes

regions in transition do not get reassigned by master when RS crashes
---------------------------------------------------------------------

                 Key: HBASE-2482
                 URL: https://issues.apache.org/jira/browse/HBASE-2482
             Project: Hadoop HBase
          Issue Type: Bug
          Components: master
    Affects Versions: 0.20.5
            Reporter: Todd Lipcon
            Priority: Critical


Very similar to HBASE-1928, but for the general case (not just ROOT/META):

If a region is in transition on a RS when the RS crashes, the master does not remove it from
regionsInTransition when processing the RS shutdown. This is fairly easy to trigger by bringing
up a RS and kill -9ing it just as it starts to get regions assigned. Those regions will get
permanently lost since they're stuck in regionsInTransition and thus don't get assigned by
the metascanner.
