Junping Du commented on YARN-2278:
----------------------------------

However, it seems we don't check version number in RPC request in server side. 
I tried to increase version number in client here, but TestRPC in yarn can 
still be successful. I think we need some fix in sever side also.

> YARN RPC should support Protocol Version in client/server

> Currently in HadoopYarnProtoRPC.java, we are put a fix version number (1) in 
> getting client proxy.
> {code}
> return RpcFactoryProvider.getClientFactory(conf).getClient(protocol, 1, addr, 
> conf);
> {code}
> In rolling-upgrade scenario, it is possible that the client and server of 
> YARN components could in different versions. We should fix this with getting 
> version number from ProtocolPB (ProtocolInfo annotation) as HDFS already did.
