-----------------------------------
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.
