Karthik Kambatla commented on YARN-2604:
----------------------------------------

The scheduler can use Math.min(max-allocation-*, largest value of 
yarn.nodemanager.resource.*) to accept applications. 

> Scheduler should consider max-allocation-* in conjunction with the largest 
> node

> If the scheduler max-allocation-* values are larger than the resources 
> available on the largest node in the cluster, an application requesting 
> resources between the two values will be accepted by the scheduler but the 
> requests will never be satisfied. The app essentially hangs forever.
