我正在尝试连接到在远程计算机上运行的hdfs示例。
我在windows机器上运行eclipse，hdfs在unix机器上运行。这是我试过的

Configuration conf = new Configuration();
         conf.set("fs.defaultFS", "hdfs://remoteHostName:portNumber");
         DFSClient client = null;
         System.out.println("try");
         try 
         {
             System.out.println("trying");   
             client = new DFSClient(conf);

        System.out.println(client);
         } 
         catch (IOException e) {

             e.printStackTrace();
        }

         finally {
             if(client!=null)
                 try {
                    client.close();
                } catch (IOException e) {

                    e.printStackTrace();
                }

         }

但这给了我以下例外

Exception in thread "main" java.lang.NoSuchMethodError: org.apache.hadoop.ipc.RPC.getProxy(Ljava/lang/Class;JLjava/net/InetSocketAddress;Lorg/apache/hadoop/security/UserGroupInformation;Lorg/apache/hadoop/conf/Configuration;Ljavax/net/SocketFactory;ILorg/apache/hadoop/io/retry/RetryPolicy;Z)Lorg/apache/hadoop/ipc/VersionedProtocol;

    at org.apache.hadoop.hdfs.DFSClient.<init>(DFSClient.java:226)

顺便说一下，我从远程机器上的hdfs-site.xml中获得了端口号
这种方法正确吗？
另外，在python中这样做会更容易吗？
编辑
注意，我确实在windows上解压了hadoop二进制文件，并相应地设置了hadoop\u home环境变量。这会引起问题吗？
