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.
