Eric Payne updated YARN-5892: ----------------------------- Description: 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} was: Currently, in the capacity scheduler, the {{minimum-user-limit-percent}} property is per queue.
