Master receives unexpected region close but doesn't do anything
---------------------------------------------------------------
Key: HBASE-3742
URL: https://issues.apache.org/jira/browse/HBASE-3742
Project: HBase
Issue Type: Bug
Affects Versions: 0.90.1
Reporter: Jean-Daniel Cryans
Fix For: 0.90.3
We got this in the context of HBASE-3741, a region was closed by a region
server but the master wasn't expecting it and didn't do anything about it. We
had to force assign it back.
