Summary: Preemption can cause capacity scheduler to show 5,000% queue absolute used capacity. Key: YARN-2285 URL: https://issues.apache.org/jira/browse/YARN-2285 Project: Hadoop YARN Issue Type: Bug Components: capacityscheduler Affects Versions: 2.5.0 Environment: Turn on CS Preemption. Reporter: Tassapol Athiapinya Attachments: preemption_5000_percent.png I configure queue A, B to have 1%, 99% capacity respectively. There is no max capacity for each queue. Set high user limit factor. Submit app 1 to queue A. AM container takes 50% of cluster memory. Task containers take another 50%. Submit app 2 to queue B. Preempt task containers of app 1 out. Turns out capacity of queue B increases to 99% but queue A has 5000% used. -- This message was sent by Atlassian JIRA (v6.2#6252)
