Wangda Tan created YARN-3153: -------------------------------- Summary: Capacity Scheduler max AM resource percentage is mis-used as ratio Key: YARN-3153 URL: https://issues.apache.org/jira/browse/YARN-3153 Project: Hadoop YARN Issue Type: Bug Reporter: Wangda Tan Assignee: Wangda Tan Priority: Critical
In existing Capacity Scheduler, it can limit max applications running within a queue. The config is yarn.scheduler.capacity.maximum-am-resource-percent, but actually, it is used as "ratio", in implementation, it assumes input will be \[0,1\]. So now user can specify it up to 100, which makes AM can use 100x of queue capacity. We should fix that. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
