Wangda Tan commented on YARN-5000:
----------------------------------

Thanks [~sunilg] for working on this fix, several comments while looking at 
screenshots.
1) Instead of showing "containers are not found", we don't have to show 
containers table.
2) Can we show application attempt status (running/finished/failed, etc.) and 
elapsed time on the app-attempt page?

Thoughts?

> If timeline server is not started, app attempt page is not getting loaded.
> In new web-ui, yarnContainer route is tightly coupled with both RM and 
> Timeline server. And if one of server is not up, page will not load. If 
> timeline server is not up, container information from RM is to be displayed.
