> Per the Apache documentation for Yarn Node Labels (http://hadoop.apache.org/docs/r2.7.3/hadoop-yarn/hadoop-yarn-site/NodeLabel.html),
queues that can only access nodes without labels are defined by setting the property "yarn.scheduler.capacity.<queue-path>.accessible-node-labels"
with space as the value.
> Reproduction Steps:
> 1. In the Capacity Scheduler view (Yarn Queue Manager), create queues q1,q2, and set
accessible node labels for root,q1,q2 but not for default queue
> 2. Since there is no way to specify a "space" as the value for accessible node labels
via Yarn Queue Manager, add this property manually via yarn configs. i.e. In Yarn -> Configs
-> Scheduler, manually add 
> yarn.scheduler.capacity.root.default.accessible-node-labels= (space after the =)
> 3. Save the configuration and restart Resource Manager as required
> 4. Return to Yarn Queue Manager, and click the default queue. It shows an error - Label
is not exist on cluster.
