> Everytime the active went down and the standby is becoming active, the app details page
in Tez shows a blank page. A refresh fixes the issue but it is likely due to the status call
throwing an error.
> This happens because, Tez view caches the RM and ATS Url in the frontend and uses it
for querying the rest of the time. So, when the active RM changes, the call still hits the
standby/killed RM and hence the UI fails.
> As for the solution, the Tez view will not cache the Urls rather query the proxy url
to talk to RM and ATS and the ATS/RM Url will be fetched every time from within the proxy.
