bq.sample mapreduce on default queue
Did this MR job submit with any specific label? like AM label or map/reduce label?

> Refreshing a queue's default node label expression does not reflect for the running applications.

> Repro Steps:
> 4 node cluster, two node labels label1 and label2. label1 is Exclusive Partition with
Node1 and Node2, label2 is Exclusive Partition with Node3 and Node4. A default queue whose
default node label expression is label1. 
> 1.Shutdown NodeManagers on label1 nodes Node1 and Node2
> 2.Submit a sample mapreduce on default queue which will stay in ACCEPTED state 
> 3.Change default node label expression for default queue to label2 in capacity-scheduler.xml
> yarn rmadmin -refreshQueues
> queue's config gets reflected to label2 as shown on RM UI queue section but job still
stays at ACCEPTED state
> 4. Submitting a new job into default queue moves into RUNNING state
