使用Idea连接阿里云搭建的Hadoop集群

使用Idea连接阿里云搭建的Hadoop集群

使用阿里云内网搭建集群后，尝试用Idea来进行远程连接并操作集群。具体的搭建流程可以参考我的另一篇博文：在阿里云上搭建Hadoop集群。

测试代码如下

package xyz.xingcang.hdfs;

import org.apache.hadoop.conf.Configuration;
import org.apache.hadoop.fs.FSDataOutputStream;
import org.apache.hadoop.fs.FileSystem;
import org.apache.hadoop.fs.Path;
import org.apache.hadoop.io.IOUtils;
import org.checkerframework.checker.units.qual.Temperature;
import org.junit.After;
import org.junit.Before;
import org.junit.Test;

import java.io.FileInputStream;
import java.io.IOException;
import java.io.PushbackReader;
import java.net.URI;
import java.net.URISyntaxException;

public class HdfsClient {
   
    private String user;
    private Configuration configuration;
    private URI uri;
    private FileSystem fileSystem;


    @Before
    public void init() throws URISyntaxException, IOException, InterruptedException {
   
        uri = new URI("hdfs://hadoop001:9820");
        configuration = new Configuration();
        configuration.set("dfs.replication", "3");
        user = "xingcang";
        fileSystem = Fil
