> Perform upgrade, dialog goes thru prepare tasks, I click to proceed. At that point, the % numbers move and I see progress in ambari-server.log but the UI list of tasks is not updating. It only shows Prepare task. Also, looks like things are coming back from REST API that show progress. It's the UI is just not updating.
> I reload my browser and then it catches up and starts showing tasks.
> What I notice: top level tasks don't show, I have to refresh browser, then the top-level will shows and the subs show.
> 1) So Prepare Backups shows
> 2) once PB is done, the next task does not show until I refresh browser
> 3) Then PB + ZooKeeper shows. once ZK is done,  the next task does not show until I refresh browser
> 4) Then PB + ZK + Core Masters shows.   once CM is done,  the next task does not show until I refresh browser
> I see this this for all top-level tasks.
