------------------------------------------------------------
By the way, the latest patch reverts the behavior of what is displayed in the
{{Max Resource}} column in the Capacity Scheduler GUI to the previous behavior.
The last active value is stored and displayed rather than being recalculated
based on current active users and resources.
- YARN-5892.008.patch (odd behavior) (User 2 is active):
||*User Name*||*Max Resource*||*Weight*||*Used Resource*||
|{panel:bgColor=yellow}User2{panel}|{panel:bgColor=yellow}<memory:7168,
vCores:1>{panel}|{panel:bgColor=yellow}0.2{panel}|{panel:bgColor=yellow}<memory:7168,
vCores:14>{panel}|
|User5|<memory:35840, vCores:1>|1.0|<memory:2560, vCores:5>|
- YARN-5892.009.patch (sane behavior) (user2 is active):
||*User Name*||*Max Resource*||*Weight*||*Used Resource*||
|{panel:bgColor=yellow}User2{panel}|{panel:bgColor=yellow}<memory:7168,
vCores:1>{panel}|{panel:bgColor=yellow}0.2{panel}|{panel:bgColor=yellow}<memory:7168,
vCores:14>{panel}|
|User5|<memory:7168, vCores:1>|1.0|<memory:2560, vCores:5>|

> Capacity Scheduler: Support user-specific minimum user limit percent

> 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}
