------------------------------

             Summary: Downgrade button does not work after restart Ambari server when upgrade
wizard was left open
                 Key: AMBARI-19657
                 URL: https://issues.apache.org/jira/browse/AMBARI-19657
             Project: Ambari
          Issue Type: Bug
          Components: ambari-web
    Affects Versions: trunk
            Reporter: Di Li
            Assignee: Di Li
             Fix For: trunk


Run express/rolling upgrade on a trunk cluster. While the upgrade wizard UI pauses on a manual
step or a failed step, restart ambari server. Once the Ambari Server restarts, reload Ambari
web UI, observe that the wizard UI pops up automatically with  the paused step showing the
Downgrade button. Clicking the downgrade button doesn't do anything in this case because the
"currentVersion" variable in the controller isn't set yet. Workaround is to close the wizard
to force the Stack/Version page to reload, then reopen the wizard and click the Downgrade
button.
