Wangda Tan commented on YARN-5892:
----------------------------------
Thanks [~eepayne] for your detailed explanations:
bq. No, that's not how it will work with this implementation.
Yeah you're correct, it works with this implementation.
bq. Instead of a warning, I will cause the parse of the CS config to fail if
weight is < 0
Sounds good.
bq. I am afraid that I disagree for reasons stated above. #2 can be addressed
with a simple check
It was a typo in my previous comment, it should be {{#1}} and as you commented,
it is not an issue.

> 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}
