> rpcTimeOut is not set up correctly in Client thus client doesn't time out

> NameNodeProxies.createNNProxyWithClientProtocol does
> {code}
> ClientNamenodeProtocolPB proxy = RPC.getProtocolProxy(
> ClientNamenodeProtocolPB.class, version, address, ugi, conf,
> NetUtils.getDefaultSocketFactory(conf),
> org.apache.hadoop.ipc.Client.getTimeout(conf), defaultPolicy,
> fallbackToSimpleAuth).getProxy();
> {code}
> which calls Client.getTimeOut(conf) to get timeout value.
> Client.getTimeOut(conf) doesn't consider IPC_CLIENT_RPC_TIMEOUT_KEY right
> now. Thus rpcTimeOut doesn't take effect for relevant RPC calls, and they
> hang!
> For example, receiveRpcResponse blocked forever at:
