> 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
> Assignee: Todd Lipcon
> Priority: Blocker

> 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.
