Wangda Tan commented on YARN-5698:
----------------------------------

Thanks [~sunilg] for working on the patch.

Few comments & suggestions:
1) Is it better to rename yarn.resourcemanager.webapp.ui2.enable to yarn.webapp.ui2.enable, since the UI is not only for resourcemanager.
2) When RM is runs on the local host, we still need to run {{corsproxy}}. Do you know what can we do to fix it?
3) A couple of renames: 
- URL endpoint: /newUI to /ui2 (consistent with config key)
- {{public WebApp start(WebApp webapp, WebAppContext context)}}, context to ui2Context

Beyond this, patch looks good. And if you have some bandwidth, could you test the patch on a distributed environment?
