>             Project: Hadoop YARN
>          Issue Type: Sub-task

> Bad queuing decisions by the LocalRMs (e.g., due to the distributed nature of 
> the scheduling decisions or due to having a stale image of the system) may 
> lead to an imbalance in the waiting times of the NM container queues. This 
> can in turn have an impact in job execution times and cluster utilization.
> To this end, we introduce corrective mechanisms that may remove (whenever 
> needed) container requests from overloaded queues, adding them to less-loaded 
> ones.
