Wangda Tan commented on YARN-3434: ---------------------------------- [~tgraves], I feel like this issue and several related issues are solved by YARN-3243 already. Could you please check if this problem is already solved? Thanks, > Interaction between reservations and userlimit can result in significant ULF > violation > -------------------------------------------------------------------------------------- > > Key: YARN-3434 > URL: https://issues.apache.org/jira/browse/YARN-3434 > Project: Hadoop YARN > Issue Type: Bug > Components: capacityscheduler > Affects Versions: 2.6.0 > Reporter: Thomas Graves > Assignee: Thomas Graves > > ULF was set to 1.0 > User was able to consume 1.4X queue capacity. > It looks like when this application launched, it reserved about 1000 > containers, each 8G each, within about 5 seconds. I think this allowed the > logic in assignToUser() to allow the userlimit to be surpassed. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
