> Corrective mechanisms for rebalancing NM container queues

> Key: YARN-2888
> URL: https://issues.apache.org/jira/browse/YARN-2888
> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: nodemanager, resourcemanager

>
> 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.
