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.
