Fixup of "missing" daughters on split is too aggressive
-------------------------------------------------------

                 Key: HBASE-3026
                 URL: https://issues.apache.org/jira/browse/HBASE-3026
             Project: HBase
          Issue Type: Bug
          Components: master
            Reporter: stack
             Fix For: 0.90.0


There is a bug in how we check for whether the daughters mentioned in parent region are present
in .META.  The check is done when we are processing a server shutdown.  We're making the mistake
of checking for presence of the daughter in the list of regions that used to live on the crashed
server BUT fact of the matter is is that the daughter could just as well be rebalanced to
another server.

The upshot is that we are inserting into .META. and trying to assign regions that are already
assigned.
