Xuan Gong commented on YARN-513:
--------------------------------
The new patch includes:
1. remove RMClient, create RMProxy, followed the pattern of NameNodeProxy,
includes several static CreateXXX() method. This will be much simpler.
2. At NodeManagerUpdaterImpl, there is not RMProxy object anymore, use
RMProxy.createRMProxy() to create ResourceTracker object directly.
3. Remove invoke method, call proxy.method() directly.
4. change the testcases, including changes localRMClient to LocalRMProxy
> Create common proxy client for communicating with RM
