>
> There are several classes in YARN’s container assignment and task scheduling
> algorithms that relate to data locality which were updated to give preference
> to running a container on other locality besides node-local and rack-local
> (like nodegroup-local). This propose to make these data structure/algorithms
> pluggable, like: SchedulerNode, RMNodeImpl, etc. The inner class
> ScheduledRequests was made a package level class to it would be easier to
> create a subclass, ScheduledRequestsWithNodeGroup.
