--------------------------------
Assignee: Eric Payne
> Capacity Scheduler Intra-queue preemption: add property to only preempt up to
> configured MULP
> ---------------------------------------------------------------------------------------------
>
> Key: YARN-7424
> URL: https://issues.apache.org/jira/browse/YARN-7424
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: capacity scheduler, scheduler preemption
> Affects Versions: 3.0.0-beta1, 2.8.2
> Reporter: Eric Payne
> Assignee: Eric Payne
>
> If the queue's configured minimum user limit percent (MULP) is something
> small like 1%, all users will max out well over their MULP until 100 users
> have apps in the queue. Since the intra-queue preemption monitor tries to
> balance the resource among the users, most of the time in this use case it
> will be preempting containers on behalf of users that are already over their
> MULP guarantee.
> This JIRA proposes that a property should be provided so that a queue can be
> configured to only preempt on behalf of a user until that user has reached
> its MULP.
