public class HdfsClient {

@Test
public void testmkdir() throws URISyntaxException, IOException, InterruptedException {

    //连接的集群nn地址
    URI uri = new URI("hdfs://master:8020");

    //创建一个配置文件
    Configuration configuration = new Configuration();

    //1、获取到了客户端对象
    FileSystem fs = FileSystem.get(uri,configuration,"root");
    //FileSystem.get(new URI("hdfs://master:9000"),new Configuration());

    //2、创建一个文件夹
    fs.mkdirs(new Path("/xiyou/huaguoshan"));

    //3、关闭资源
