Hudson commented on YARN-3434: ------------------------------ SUCCESS: Integrated in Hadoop-Mapreduce-trunk-Java8 #193 (See [https://builds.apache.org/job/Hadoop-Mapreduce-trunk-Java8/193/]) Moved YARN-3434. (Interaction between reservations and userlimit can result in significant ULF violation.) From 2.8.0 to 2.7.1 (wangda: rev 1952f88889395870e7b631d43418e075e774b9d2) * hadoop-yarn-project/CHANGES.txt > 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 > Fix For: 2.8.0, 2.7.1 > > Attachments: YARN-3434-branch2.7.patch, YARN-3434.patch, > YARN-3434.patch, YARN-3434.patch, YARN-3434.patch, YARN-3434.patch, > YARN-3434.patch, YARN-3434.patch > > > 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)
