Junping Du commented on YARN-2278:
----------------------------------
{code}
"version = RPC.getProtocolVersion(protocolPB) + 1;"
{code}
This is for test purpose as I mentioned above. I would expect a "version
mismatch" exception is thrown out like what we did at HADOOP-10729, but didn't
run to it.
> YARN RPC should support Protocol Version in client/server

> Key: YARN-2278
> URL: https://issues.apache.org/jira/browse/YARN-2278
> Project: Hadoop YARN
> Issue Type: Sub-task
> Affects Versions: 2.4.1
> Reporter: Junping Du

>
> 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.
