Sandy Ryza commented on YARN-2811: ---------------------------------- Cool, thanks for the updated patch. Are you able to add a test to verify the behavior? A couple nits: {code} + if (Resources.fitsIn(queue.getResourceUsage(), queue.scheduler + .getAllocationConfiguration().getMaxResources(queue.getName()))) { {code} Since we're in FairScheduler, can we just access the allocation configuration directly? {code} //Don't hold the reservation if queue reaches its maximum {code} Double slashes should have a space after them. > Fair Scheduler is violating max memory settings in 2.4 > ------------------------------------------------------ > > Key: YARN-2811 > URL: https://issues.apache.org/jira/browse/YARN-2811 > Project: Hadoop YARN > Issue Type: Bug > Affects Versions: 2.4.0 > Reporter: Siqi Li > Assignee: Siqi Li > Attachments: YARN-2811.v1.patch, YARN-2811.v2.patch, > YARN-2811.v3.patch > > > This has been seen on several queues showing the allocated MB going > significantly above the max MB and it appears to have started with the 2.4 > upgrade. It could be a regression bug from 2.0 to 2.4 -- This message was sent by Atlassian JIRA (v6.3.4#6332)
