Jason Lowe updated YARN-236:
----------------------------
Attachment: YARN-236.patch
Patch to have the proxy servlet fallback to the RM's webpage for the app if no
tracking URL is available.
No unit test, but I manually tested both visiting the proxy URI before the app
starts running and after an app crashed on startup. In both cases the page was
redirected to the RM's webpage for the app.
> RM should point tracking URL to RM web page when app fails to start

> Similar to YARN-165, the RM should redirect the tracking URL to the specific
> app page on the RM web UI when the application fails to start. For example,
> if the AM completely fails to start due to bad AM config or bad job config
> like invalid queuename, then the user gets the unhelpful "The requested
> application exited before setting a tracking URL".
> Usually the diagnostic string on the RM app page has something useful, so we
> might as well point there.
