> 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.
