A value of -1 disables this. yarn.scheduler.capacity.root.default.state RUNNING The state of the default queue. State can be one of RUNNING or STOPPED. yarn.scheduler.capacity.root.default.acl_submit_jobs * The ACL of who can submit jobs to the default queue. yarn.scheduler.capacity.root.default.acl_administer_jobs * The ACL of who can administer jobs on the default queue. yarn.scheduler.capacity.root.acl_administer_queues * The ACL for who can administer this queue i.e. change sub-queue allocations.
