             Summary: Exiting Add Hosts Wizard during deploy causes Hosts table to break - then the wizard got stuck trying to add already-added host
                 Key: AMBARI-4923
                 URL: https://issues.apache.org/jira/browse/AMBARI-4923
             Project: Ambari
          Issue Type: Task
          Components: client
    Affects Versions: 1.5.0
            Reporter: Antonenko Alexander
            Assignee: Antonenko Alexander
             Fix For: 1.5.0


During the Deploy phase of the Add Hosts Wizard, I hit the X on the top-right corner.  This showed a Hosts table with strange data (no hostnames, etc - see screenshot).
After this, I launched Add Hosts wizard after some time (after the install tasks were done, I believe).
Now, the wizard tries to continue from the Review step and gets stuck.  Refreshing the page, logging out, etc, doesn't help.
At this point, the user needs to go back to Step 1 of the wizard from the left nav to clear out this weird state.

* We should add a way to Abort the wizard with a confirmation, so that it doesn't get stuck (to clear the "persist" state and launch the wizard from Step 1 with no artifacts from the previous run).
* We can force page refresh upon closing the wizard to prevent the broken hosts table problem.
