>             Project: Hadoop YARN
>          Issue Type: Improvement

> When assignMultiple is turned on, today the number of containers allocated to node within
a single heartbeat is determined by maxAssign. Picking a higher value for this prevents the
spreading of the workload, and a smaller number leads to slow ramp up. 
> The proposal is to make it dynamic - half of the unallocated resources on the node.
