Configure Priority ACLs to ensure that only select users can submit applications with
a specified priority to a queue. You must configure these Priority ACLs at the leaf
queue-level.
If ACLs are already configured for user access to a leaf queue, then the Priority
ACLs for the queue can include only those users with access to that queue.

In Capacity Scheduler Configuration Advanced Configuration Snippet (Safety Valve) field, add the following:
Name: yarn.scheduler.capacity.<leaf-queue-path>.acl_application_max_priority
Value: [user={username} group={groupname} max_priority={priority} default_priority={priority}]
Description: The ACL of users who can submit applications with configured priority.
The following example shows how you can configure Priority ACLs for a user
maria and for the users of a group
hadoop:
Name: yarn.scheduler.capacity.root.queue1.acl_application_max_priority
Value: [user=maria group=hadoop max_priority=7 default_priority=4]
The user maria and the users of the hadoop group can submit applications with a maximum priority of 7.
