Subject [jira] [Created] (HBASE-6483) Fully enable ServerShutdownHandler after master joins the cluster

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

             Summary: Fully enable ServerShutdownHandler after master joins the cluster
                 Key: HBASE-6483
                 URL: https://issues.apache.org/jira/browse/HBASE-6483
             Project: HBase
          Issue Type: Sub-task
            Reporter: Jimmy Xiang


Once ROOT and META are assigned, ServerShutdownHandler is enabled. So that we can handle meta/root
region server failure before joinCluster is completed. However, we can hold ServerShutdownHandler
a little bit more for the user region assignments, i.e. doesn't assign user regions before
joinCluster is returned. If so, we can avoid some region assignments racing: same regions
are trying to be assigned in both joinCluster and ServerShutdownHandler.
