> 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?
