ZhangShenao opened a new issue #870: Redundant Config in RemotingUtil?
URL: https://github.com/apache/rocketmq/issues/870
 
 
   The method connect in is as follows:
   `public static SocketChannel connect(SocketAddress remote, final int 
timeoutMillis) {
           SocketChannel sc = null;
           try {
               sc = SocketChannel.open();
               sc.configureBlocking(true);
               sc.socket().setSoLinger(false, -1);
               sc.socket().setTcpNoDelay(true);
               sc.socket().setReceiveBufferSize(1024 * 64);
               sc.socket().setSendBufferSize(1024 * 64);
               sc.socket().connect(remote, timeoutMillis);
               sc.configureBlocking(false);
               return sc;
           } catch (Exception e) {
               if (sc != null) {
                   try {
                       sc.close();
                   } catch (IOException e1) {
                       e1.printStackTrace();
                   }
               }
           }
   
           return null;
       }`
   Since we are using a non-blocking mode , why config blocking true in advance?
