> Put /scheduler-ui behind knox-proxy in YARN UI V2
> -------------------------------------------------
>
> Key: KNOX-3286
> URL: https://issues.apache.org/jira/browse/KNOX-3286
> Project: Apache Knox
> Issue Type: Improvement
> Reporter: chhinlinghean
> Priority: Major
> Fix For: 3.0.0
>
> Time Spent: 0.5h
> Remaining Estimate: 0h
>
> https://issues.apache.org/jira/browse/YARN-11938 integrate scheduler-ui in
> YARN UIV2.
> It works perfectly in a non-secure cluster.
> However, in a secure cluster with KNOX:
> - When user view YARN UIV2
> - Navigate to Scheduler-UI navigation bar
> - It will redirect user to \{knox-gateway}/scheduler-ui
> - Which will throw 404 status code because it is not behind knox-proxy
> - In secured cluster, yarn-scheduler-ui is served under /yarn-scheduler-ui
> according to this ticket https://issues.apache.org/jira/browse/KNOX-3249
> Thus the rewrite.xml should be updated for YARNUIV2 to put the /scheduler-ui
> behind KNOX proxy to /yarn-scheduler-ui when user click on navigation bar
> Scheduler UI.
