Deegue opened a new pull request #4118: URL: https://github.com/apache/hadoop/pull/4118
### Description of PR We can enable this feature by setting `yarn.scheduler.fair.app-submission-limit-enabled` to true, and control the maximum resources ratio an application can use by adjusting `<maxAppShare>` of each queue. It resolves the problem applications starve when a single application takes all resources of the queue. It can be quite effective when all tasks of a queue need to be treated fairly. ### How was this patch tested? UTs and manual -- This is an automated message from the Apache Git Service.
