> There are several classes in YARN=E2=80=99s container assignment and task=
 scheduling algorithms that relate to data locality which were updated to g=
ive preference to running a container on other locality besides node-local =
and rack-local (like nodegroup-local). This propose to make these data stru=
cture/algorithms pluggable, like: SchedulerNode, RMNodeImpl, etc. The inner=
 class ScheduledRequests was made a package level class to it would be easi=
er to create a subclass, ScheduledRequestsWithNodeGroup.
