> 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.
