Junping Du updated MAPREDUCE-4309:
----------------------------------
Attachment: MAPREDUCE-4309-v4.patch
In v4 patch, fix two minor issues in previous patch:
1. In getting declared constructor, use class from string rather than getting
class from object (the later could be sub class which will be failed to get
constructor).
2. Keep some variables "private" to get rid of inconsistent synchronized issue
that found by FindBugs in previous patch.
> Make locatlity in YARN's container assignment and task scheduling pluggable
> for other deployment topology

> 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.
