Subject [jira] [Updated] (YARN-5892) Support user-specific minimum user limit percentage in Capacity Scheduler
Date Sat, 15 Jul 2017 22:20:00 GMT

     [ https://issues.apache.org/jira/browse/YARN-5892?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Eric Payne updated YARN-5892:
-----------------------------
    Attachment: YARN-5892.branch-2.8.016.patch

I cherry-picked the trunk commit to branch-2 for this JIRA.

I am now attaching YARN-5892.branch-2.8.016.patch, which had to be refactored from the branch-2
version, due to the differences in branch-2.8.

> 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}
