Sunil G commented on YARN-6052: ------------------------------- Thanks [~Prabhu Joseph] for pointing out. > Yarn RM UI % of Queue at application level is wrong > --------------------------------------------------- > > Key: YARN-6052 > URL: https://issues.apache.org/jira/browse/YARN-6052 > Project: Hadoop YARN > Issue Type: Bug > Affects Versions: 2.7.3 > Reporter: Prabhu Joseph > Assignee: Prabhu Joseph > Priority: Minor > Attachments: RM_UI.png > > > Test Case: > yarn.scheduler.capacity.root.capacity=100 > yarn.scheduler.capacity.root.queues=default,dummy > yarn.scheduler.capacity.root.default.capacity=20 > yarn.scheduler.capacity.root.dummy.capacity=80 > yarn.scheduler.capacity.root.dummy.child.capacity=50 > yarn.scheduler.capacity.root.dummy.child2.capacity=50 > Memory Total is 20GB, default queue share is 4GB and dummy queue share is > 16GB. Child and Child1 queue gets 8GB share each. > A map reduce job is submitted to child2 queue which asks 2 containers of 512 > MB. Now cluster Memory Used is 1GB. > Root queue usage = 100 / (total memory / used memory) = 100 / (20 / 1) = 5% > Dummy queue usage = 100 / (16 /1) = 6.3% > Dummy.Child2 queue usage = 100 / (8/1) = 12.5% > At application level, % of queue is calculated as 100 / (50% of root queue > capacity) = 100 / (50% of 20GB) = 10.0 instead of > 100 / (50% of dummy queue capacity) = 100 / (50% of 16GB) = 100 / 8 = 12.5 > Where 50% is dummy.child2 capacity > Attached RM UI screenshot. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
