Jason Lowe commented on YARN-7422:
----------------------------------
I am a little confused on the goals of this JIRA. This cannot be solved solely
on the AM side. The AM runs on nodes that can fail at any time without giving
the AM any chance to perform corrective measures regarding the tracking URL.
AM behavior could make this better but it cannot be completely solved there.
Completely solving this requires changes on the YARN server side because the AM
could catastrophically fail without executing any shutdown code. One simple
method that would work for Tez and possibly other frameworks would be
supporting a history URL during registration in addition to the one already
supported at unregistration. Then as long as the AM registers we have a place
to direct users after the app completes even if the AM subsequently crashes
spectacularly and never unregisters. If the AM crashes before it even
registers then I would argue the existing AHS-only history behavior should be
sufficient since it's not likely the AM had a chance to do any
framework-specific behavior before it registered.

> Key: YARN-7422
> URL: https://issues.apache.org/jira/browse/YARN-7422
> Project: Hadoop YARN
> Issue Type: Bug
> Components: yarn
> Affects Versions: 2.8.1
> Reporter: Kuhu Shukla
> Priority: Major
>
> In cases where AM fails fatally, the AHS page's history link does not work
> since AM was not able to update the trackingURL for the job. This JIRA is to
> track any last attempt effort we can do from the AM to allow a tracking URL
> in cases where the AM failure does not occur immediately at start up. Any
> ideas and corrections would be appreciated.
