> URL: https://issues.apache.org/jira/browse/AMBARI-13612
> Project: Ambari
> Issue Type: Bug
> Components: ambari-views
> Reporter: DIPAYAN BHOWMICK
> Assignee: DIPAYAN BHOWMICK
> Fix For: 2.1.3

> Attachments: AMBARI-13612_branch-2.1.patch

>
> 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.
