> While administering a cluster using multiple queues, administrators feel a
> need to refresh queue properties on the fly without needing to restart the
> JobTracker. This is partially supported for some properties such as queue
> ACLs (HADOOP-5396) and state (HADOOP-5913). The idea is to extend the
> facility to refresh other queue properties as well, including scheduler
> properties.
