Subject [jira] Created: (HADOOP-1780) [hbase] Regions are still being doubly assigned

[hbase] Regions are still being doubly assigned
-----------------------------------------------

                 Key: HADOOP-1780
                 URL: https://issues.apache.org/jira/browse/HADOOP-1780
             Project: Hadoop
          Issue Type: Bug
          Components: contrib/hbase
            Reporter: stack
            Priority: Minor


HADOOP-1747 fixed an obvious failure in assignment code where regions were being handed out
to multiple hosts by the twos and threes but a bug remains.  Over 260 assignments in a recent
upload to a cluster of 4 machines, two regions were assigned to two different hosts.  Here's
log snippet from master showing region being assigned to two different hosts:
