             Summary: Add support for marking hbase RS instances as DRAINING before decommission
                 Key: AMBARI-4499
                 URL: https://issues.apache.org/jira/browse/AMBARI-4499
             Project: Ambari
          Issue Type: Bug
          Components: controller
    Affects Versions: 1.5.0
            Reporter: Sumit Mohanty
            Assignee: Sumit Mohanty
             Fix For: 1.5.0


Hbase decommission is actually a graceful stop under the cover. One critical component of
graceful stop is to mark candidate region server instances as "draining". This is required
when more than one node is being stopped so that regions being moved out of one node do not
end up on the another node that is also a candidate of graceful stop.
