[jira] [Created] (AMBARI-5392) Recommend putting Region Server in Maintenance Mode when Decommissioning Region Server

Andrii Babiichuk created AMBARI-5392:
----------------------------------------

             Summary: Recommend putting Region Server in Maintenance Mode when Decommissioning Region Server
                 Key: AMBARI-5392
                 URL: https://issues.apache.org/jira/browse/AMBARI-5392
             Project: Ambari
          Issue Type: Improvement
          Components: client
    Affects Versions: 1.6.0
            Reporter: Andrii Babiichuk
            Assignee: Andrii Babiichuk
             Fix For: 1.6.0


Hbase doesn't support decommission natively - instead we just do a graceful shutdown. This means on a HBase restart, the region server will restart. Ambari will cover for this by recommending to put region server in maintenance mode.
