> Reservations continue looking for one app causes other apps to starve

> Key: YARN-4610
> URL: https://issues.apache.org/jira/browse/YARN-4610
> Project: Hadoop YARN
> Issue Type: Bug
> Components: capacityscheduler
> Affects Versions: 2.7.1
> Reporter: Jason Lowe
> Assignee: Jason Lowe
> Priority: Blocker
> Attachments: YARN-4610.001.patch, YARN-4610.branch-2.7.001.patch

>
> CapacityScheduler's LeafQueue has "reservations continue looking" logic that
> allows an application to unreserve elsewhere to fulfil a container request on
> a node that has available space. However in 2.7 that logic seems to break
> allocations for subsequent apps in the queue. Once a user hits its user
> limit, subsequent apps in the queue for other users receive containers at a
> significantly reduced rate.
