Master dying while going to close a region can leave it in transition forever
-----------------------------------------------------------------------------

                 Key: HBASE-4739
                 URL: https://issues.apache.org/jira/browse/HBASE-4739
             Project: HBase
          Issue Type: Bug
    Affects Versions: 0.90.4
            Reporter: Jean-Daniel Cryans
            Priority: Minor
             Fix For: 0.92.0, 0.94.0, 0.90.5


I saw this in the aftermath of HBASE-4729 on a 0.92 refreshed yesterday, when the master died
it had just created the RIT znode for a region but didn't tell the RS to close it yet.

When the master restarted it saw the znode and started printing this:

transition timed out:  TestTable,0007560564,1320253568406.f76899564cabe7e9857c3aeb526ec9dc.
state=CLOSING, ts=1320253605285, server=sv4r11s38,62003,1320195046948
2011-11-03 00:02:49,130 INFO org.apache.hadoop.hbase.master.AssignmentManager: Region has
been CLOSING for too long, this should eventually complete or the server will expire, doing
nothing

It's never going to happen, and it's blocking balancing.

I'm marking this as minor since I believe this situation is pretty rare unless you hit other
bugs while trying out stuff to root bugs out.
