> 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:
> {code}
> Thread 16127: (state = BLOCKED)
