Introduction

In this page you can find the example usage for org.apache.hadoop.net NetUtils connect.

Prototype

public static void connect(Socket socket, SocketAddress endpoint, SocketAddress localAddr, int timeout)
        throws IOException

Document

Like NetUtils#connect(Socket,SocketAddress,int) but also takes a local address and port to bind the socket to.

@Override
// RemotePeerFactory
public Peer newConnectedPeer(InetSocketAddress addr, Token<BlockTokenIdentifier> blockToken,
        DatanodeID datanodeId) throws IOException {
    Peer peer = null;/*from  w w w .ja  v  a 2s  . c  om*/
    boolean success = false;
    Socket sock = null;
    try {
        sock = socketFactory.createSocket();
        NetUtils.connect(sock, addr, getRandomLocalInterfaceAddr(), dfsClientConf.getSocketTimeout());
        peer = TcpPeerServer.peerFromSocketAndKey(saslClient, sock, this, blockToken, datanodeId);
        peer.setReadTimeout(dfsClientConf.socketTimeout());
        success = true;
        return peer;
    } finally {

            IOUtils.cleanup(LOG, peer);
            IOUtils.closeSocket(sock);
        }
