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

Thanks [~leftnoteasy] for the reminder. Quickly checked failed cases, not 
related. Fixed checkstyle issue and re-upload the patch.

> Add unit test to validate queue priority preemption works under node 
> partition.

> Add unit test to validate queue priority preemption works under node 
> partition.
> Test configuration:
>  queue A (capacity=50, priority=1)
>  queue B (capacity=50, priority=2)
>  both have accessible-node-labels set to x
>  A.accessible-node-labels.x.capacity = 50
>  B.accessible-node-labels.x.capacity = 50
>  Along with this pre-emption related properties have been set.
> Test steps:
>  - Submit an application A1 to B, with am-container = container = 4096, no. 
> of containers = 4
>  - Submit an application A2 to A, with am-container = 1024, container = 2048, 
> no of containers = (NUM_NM-1)
>  - Kill application A1
>  - Submit an application A3 to B with am-container=container=5210, no. of 
> containers=NUM_NM
>  - Expectation is that containers are pre-empted from application A2 to A3
