> In our cluster we are seeing available memory and cores being negative. 
> Initial inspection:
> Scenario no. 1: 
> In capacity scheduler the method allocateContainersToNode() checks if 
> there are excess reservation of containers for an application, and they are 
> no longer needed then it calls queue.completedContainer() which causes 
> resources being negative. And they were never assigned in the first place. 
> I am still looking through the code. Can somebody suggest how to simulate 
> excess containers assignments ?
