Subject [jira] [Created] (AMBARI-13612) Add RM and ATS Proxy Urls to Ambari Tez

DIPAYAN BHOWMICK created AMBARI-13612:
-----------------------------------------

             Summary: Add RM and ATS Proxy Urls to Ambari Tez
                 Key: AMBARI-13612
                 URL: https://issues.apache.org/jira/browse/AMBARI-13612
             Project: Ambari
          Issue Type: Bug
          Components: ambari-views
            Reporter: DIPAYAN BHOWMICK
             Fix For: 2.1.3


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.
