@Test

    // here we do not have to config TCP_NDELAY settings, since they should be
    // active by default
    testConf.set(HADOOP_RPC_SOCKET_FACTORY_CLASS_DEFAULT_KEY, SocketFactoryWrapper.class.getName());

    SocketFactory defaultFactory = NetUtils.getDefaultSocketFactory(testConf);
    LOG.info("Socket factory is " + defaultFactory.getClass().getName());
    MiniDFSCluster dfsCluster = new MiniDFSCluster.Builder(testConf).numDataNodes(3).build();
    dfsCluster.waitActive();// w  w  w  .  j ava  2  s  . c o  m

    DistributedFileSystem dfs = dfsCluster.getFileSystem();

    try {
