> private void initDataXceiver(Configuration conf) throws IOException {
> // find free port or use privileged port provided
> TcpPeerServer tcpPeerServer;
> if (secureResources != null) {
> tcpPeerServer = new TcpPeerServer(secureResources);
> } else {
> tcpPeerServer = new TcpPeerServer(dnConf.socketWriteTimeout,
> DataNode.getStreamingAddr(conf));
> }
>
> tcpPeerServer.setReceiveBufferSize(HdfsConstants.DEFAULT_DATA_SOCKET_SIZE);
> {code}
> The last line sets SO_RCVBUF explicitly, thus disabling tcp auto-tuning on
> some system.
> Shall we make this behavior configurable?
