------------------------------

FAILURE: Integrated in Hadoop-Yarn-trunk #737 (See 
[https://builds.apache.org/job/Hadoop-Yarn-trunk/737/])
YARN-2824. Fixed Capacity Scheduler to not crash when some node-labels are not 
mapped to queues by making default capacities per label to be zero. Contributed 
by Wangda Tan. (vinodkv: rev 2ac1be7dec4aef001e3162e364249933b2c4a6c4)

> In existing Capacity Scheduler behavior, if user doesn't specify capacity of 
> label, queue initialization will be failed. That will cause queue refreshment 
> failed when add a new label to node labels collection and doesn't modify 
> capacity-scheduler.xml.
> With this patch, capacity of labels should be explicitly set if user want to 
> use it. If user doesn't set capacity of some labels, we will treat such 
> labels are unused labels.
