MaintMode
                 Key: AMBARI-5018
                 URL: https://issues.apache.org/jira/browse/AMBARI-5018
             Project: Ambari
          Issue Type: Bug
          Components: client
    Affects Versions: 1.5.0
            Reporter: Andrii Babiichuk
            Assignee: Andrii Babiichuk
            Priority: Critical
             Fix For: 1.5.0


1) Put HDFS in MM
2) Try to issue a rolling restart
3) The ui says there are no datanodes to perform rolling restart.
Hosts and host-components that in MM (because of host or host-component MM) 
should not respond to rolling restart. But when a service is in MM, you should 
still be able to rolling restart it's components.
