> Improve Locality Scheduling when cluster is busy
> ------------------------------------------------
>
> Key: YARN-9671
> URL: https://issues.apache.org/jira/browse/YARN-9671
> Project: Hadoop YARN
> Issue Type: Improvement
> Affects Versions: 2.10.0, 3.3.0
> Reporter: Muhammad Samir Khan
> Assignee: Muhammad Samir Khan
> Priority: Major
> Attachments: YARN-9671.001.patch
>
>
> When a cluster is very busy, scheduling opportunities are few and far
> between. Scheduling opportunities are how an application knows when to give
> up looking for decent locality.
> It doesn't make sense to work hard waiting for locality when the odds of it
> coming are very small and it may actually take a very long time to actually
> give up.
> This causes the priority of queues to be violated which is the last thing we
> want to do when the cluster is full.
> Add a mode to disable skipping locality when cluster is busy.
