-------------------------------
Attachment: YARN-5056.patch
> Expose demand at the queue level for FairScheduler
> --------------------------------------------------
>
> Key: YARN-5056
> URL: https://issues.apache.org/jira/browse/YARN-5056
> Project: Hadoop YARN
> Issue Type: Improvement
> Affects Versions: 2.7.2
> Reporter: Daniel Weeks
> Priority: Minor
> Attachments: YARN-5056.patch
>
>
> There currently isn't a way to determine where demand is coming from within
> the scheduler. Issues like YARN-2408 proposed a more detailed way to expose
> this information, but it's very easy to expose this at a queue level by
> simply including the queue demand, which is a good indicator of where
> resources requests are coming from (at least at the queue level).
> This will help to better understand metrics like "containersPending" and
> where resource requests are originating.
