Thomas Graves created YARN-3434: ----------------------------------- Summary: 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)
