             Summary: NameNode HA Wizard: allow the user to exit out of the wizard with a warning pointing to manual rollback steps
                 Key: AMBARI-3405
                 URL: https://issues.apache.org/jira/browse/AMBARI-3405
             Project: Ambari
          Issue Type: Task
          Components: client
    Affects Versions: 1.4.1
            Reporter: Antonenko Alexander
            Assignee: Antonenko Alexander
             Fix For: 1.4.1


1) Add "X" on all pages in the "Enable HA" wizard
2) Remove the "Rollback" button
3) Up until (and including) the "Create Checkpoint" page, clicking on the X just dismisses the wizard (as it does today)
4) If the user has started the "Configure Components" stage in the wizard (which means: Ambari has failed after actually performing changes), when the user clicks the X, the user will be warned with the following message:
* You are in the process of enabling NameNode HA.  If you exit now, you *must* follow manual instructions to revert back to the non-HA setup: \[link to doc - target="_blank"\].  Are you sure you want to exit the wizard?
