``我想像这样使用javajast连接到hdfs

Configuration conf = new Configuration();
        FileSystem fileSystem = FileSystem.get(new URI("hdfs://c7301.ambari.apache.org:8020"),conf);
        if(fileSystem instanceof DistributedFileSystem) {
            System.out.println("HDFS is the underlying filesystem");
        }
        else {
            System.out.println("Other type of file system "+fileSystem.getClass());
        }

它会抛出错误

Exception in thread "main" org.apache.hadoop.ipc.RemoteException: Server IPC version 9 cannot communicate with client version 4

I tried different solutions to the problem, but nothing helped.

它是我的pom.xml文件
