-----------------------------------------
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.
