> Currently, in the capacity scheduler, the {{minimum-user-limit-percent}} 
> property is per queue. A cluster admin should be able to set the minimum user 
> limit percent on a per-user basis within the queue.
> This functionality is needed so that when intra-queue preemption is enabled 
> (YARN-4945 / YARN-2113), some users can be deemed as more important than 
> other users, and resources from VIP users won't be as likely to be preempted.
> For example, if the {{getstuffdone}} queue has a MULP of 25 percent, but user 
> {{jane}} is a power user of queue {{getstuffdone}} and needs to be guaranteed 
> 75 percent, the properties for {{getstuffdone}} and {{jane}} would look like 
> this:
> {code}
>   <property>
>     
> <name>yarn.scheduler.capacity.root.getstuffdone.minimum-user-limit-percent</name>
>     <value>25</value>
>   </property>
>   <property>
>     
> <name>yarn.scheduler.capacity.root.getstuffdone.jane.minimum-user-limit-percent</name>
>     <value>75</value>
>   </property>
> {code}
