Wangda Tan commented on YARN-5000:
----------------------------------
[~sunilg],
Tested the patch, haven't done deep tests, some comments so far
1) When I try the patch, run RM without TS/NM. The application is in ACCEPTED
state, but the application page has multiple entries of attempt: (see
[attachment|https://issues.apache.org/jira/secure/attachment/12802571/screenshot-1.png]),
(This only happens when I access RM hosted page at localhost:8288, probably
caused by auto/hash issue which is mentioned by you at:
https://issues.apache.org/jira/browse/YARN-4515?focusedCommentId=15269292&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15269292).
2) When an application is running (without enable TS, but NM is running). I get
following intermittent exception when keep refreshing page at:
{{http://localhost:4200/yarnAppAttempt/appattempt_1462494543748_0004_000001
(replace by your attempt ID}}

502 (Bad Gateway)
{code}
3) (MINOR), I can get this error at console when TS is not enabled:
{{jquery.js:8630 GET
http://localhost:1337/localhost:8188/ws/v1/applicationhistory/apps/applicat…494543748_0004/appattempts/appattempt_1462494543748_0004_000001/containers
502 (Bad Gateway)}}, probably we should not show such message
For code implementation, some comments so far:
1) Instead of returning object with id="dummy" and check "dummy" everywhere, is
it possible to return an empty array? Which may be more clear.

> 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.
