Wangda Tan commented on YARN-5892: ---------------------------------- Linked this JIRA to YARN-5889, I think this is more like a special case of YARN-5889, but we need to make API to be extensible and easier to use. + [~sunilg] > Capacity Scheduler: Support user-specific minimum user limit percent > -------------------------------------------------------------------- > > Key: YARN-5892 > URL: https://issues.apache.org/jira/browse/YARN-5892 > Project: Hadoop YARN > Issue Type: Improvement > Components: capacityscheduler > Reporter: Eric Payne > > 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} -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
