Horton工作，Java连接拒绝例外

Question

我遇到连接拒绝错误的问题，我试图使用Horton作为Hadoop服务器进行项目测试但是我收到以下错误：

    java.net.ConnectException: Call From PC/192.168.56.1 to          192.168.0.3:54310 failed on connection exception: java.net.ConnectException: Connection refused: no further information; For more details see:  http://wiki.apache.org/hadoop/ConnectionRefused

查看维基后，我可以完成所有步骤，包括Telnet到服务器。

设置是 VM虚拟盒与Horton在192.168.0.3上的桥接连接上运行 与我的本地连接尝试运行以下Java代码。

    //1. Get the instance of COnfiguration
    Configuration configuration = new Configuration();
    //2. Create an InputStream to read the data from local file
    //3. Get the HDFS instance
    FileSystem hdfs = FileSystem.get(new URI("hdfs://192.168.0.3:54310"), configuration);
    //4. Open a OutputStream to write the data, this can be obtained from the FileSytem
    outputStream = hdfs.create(new Path("hdfs://192.168.0.3:54310/user/hadoop/raw/" + dateToday + "//" + timeStamp.getName()),
                            new Progressable() {
                                @Override
                                public void progress() {
                                    System.out.println("....");
                                }
                            });

在尝试连接之前，有没有办法让Java程序登录Horton服务器？
