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

             Summary: SSH should retry in case failed to assign regions
                 Key: HBASE-12196
                 URL: https://issues.apache.org/jira/browse/HBASE-12196
             Project: HBase
          Issue Type: Bug
            Reporter: Jimmy Xiang
            Assignee: Jimmy Xiang
             Fix For: 2.0.0, 0.99.1


If there is only master alive, all regionservers are down, SSH can't find a plan to assign user regions. In this case, SSH should retry.
