Date Tue, 30 May 2017 19:57:04 GMT
Vitaly Brodetskyi created AMBARI-21148:
------------------------------------------

             Summary: Add a flag to indicate NN restart is rolling
                 Key: AMBARI-21148
                 URL: https://issues.apache.org/jira/browse/AMBARI-21148
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
    Affects Versions: 3.0.0
            Reporter: Vitaly Brodetskyi
            Assignee: Vitaly Brodetskyi
            Priority: Critical
             Fix For: 3.0.0


If restart is rolling stack script should wait for NN to be out of safemode with large timeout.
Rolling indicates its an HDFS level restart so NN restart needs to be up and accepting requests
before we move on.
