[jira] [Created] (YARN-3955) Support for priority ACLs in CapacityScheduler

Sunil G created YARN-3955:
-----------------------------

             Summary: Support for priority ACLs in CapacityScheduler
                 Key: YARN-3955
                 URL: https://issues.apache.org/jira/browse/YARN-3955
             Project: Hadoop YARN
          Issue Type: Sub-task
          Components: capacityscheduler
    Affects Versions: 2.7.1
            Reporter: Sunil G
            Assignee: Sunil G


Support will be added for User-level access permission to use different application-priorities. This is to avoid situations where all users try running max priority in the cluster and thus degrading the value of priorities.

Access Control Lists can be set per priority level within each queue. Below is an example configuration that can be added in capacity scheduler configuration
file for each Queue level.
yarn.scheduler.capacity.root.<queue_name>.<priority>.acl=user1,user2
