Sunil G commented on YARN-7338:
-------------------------------
Thanks [~eyang] for clarifying.
As mentioned earlier, when client access ui2 from {{/ui2}} endpoint, it just
downloads the static pages. UI2 accesses RM and NM REST end points for getting
apps, queues metrics etc.
For logs etc, we still use existing RM and NM old UI links itself. Hence logs
are not coming in this scope.
My point is that, UI2 web endpoint does not serve any REST points or running
any server code. So do we need to have this filter for ui2 ?

> Opening jira as suggested b [~eyang] on the thread for merging YARN-3368 (new
> web UI) to branch2

> ----------
> Ui2 does not seem to support same origin policy for cross site scripting
> prevention.
> The following parameters has no effect for /ui2:
> hadoop.http.cross-origin.enabled = true
> yarn.resourcemanager.webapp.cross-origin.enabled = true
> This is because ui2 is designed as a separate web application. WebFilters
> setup for existing resource manager doesn’t apply to the new web application.
> Please open JIRA to track the security issue and resolve the problem prior to
> backporting this to branch-2.
> This would minimize the risk to open up security hole in branch-2.
