             Summary: Express Upgrade: didn't finalize HDFS, improve robustness for HA
                 Key: AMBARI-13913
                 URL: https://issues.apache.org/jira/browse/AMBARI-13913
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
    Affects Versions: 2.2.0, 2.1.3
            Reporter: Alejandro Fernandez
            Assignee: Alejandro Fernandez
             Fix For: 2.2.0, 2.1.3


For ExpressUpgrade,

1. We started the NameNodes with "-rollingUpgrade started" but were calling the wrong finalize command, "-finalizeUpgrade" instead of "-rollingUpgrade finalize".
2. In HA, if safemode was already on, then the prepare step would fail since the grep command reported an error.
3. In HA, we now check both NameNodes to come out of safemode. Before, this would only run on the active one.
