Wangda Tan commented on YARN-5000:
----------------------------------
A couple of comments about implementation:
1) Instead of following logic:
{code}
75 if (url == undefined) {
76 url = "Not Available";
77 }
78 return url != "Not Available";
{code}
Can we just return {{url != undefined}} ?
2) yarn-app.js is still using dummy, could we change it to empty array
3) A coupld of tabs found in your patch, could you double check it?
Will try this patch again after YARN-4515 get in

> 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.
