------------------------------

             Summary: Region mover script sometimes reports stuck region where only one server was involved
                 Key: HBASE-15815
                 URL: https://issues.apache.org/jira/browse/HBASE-15815
             Project: HBase
          Issue Type: Bug
    Affects Versions: 1.1.2
            Reporter: Ted Yu
            Priority: Minor


Sometimes we saw the following in output from region mover script:
{code}

{code}
There was only one server involved.
Since the name of region was not printed, it makes debugging hard to do.
