咨询，往HDFS上复制文件失败！

package Hadoop.HDFS;

import java.io.BufferedInputStream;
import java.io.FileInputStream;
import java.io.InputStream;
import java.io.OutputStream;
import java.net.URI;

import org.apache.hadoop.conf.Configuration;
import org.apache.hadoop.fs.FileSystem;
import org.apache.hadoop.fs.Path;
import org.apache.hadoop.io.IOUtils;
import org.apache.hadoop.util.Progressable;

public class App2 {
public static void main(String[] args) throws Exception {
String locaSrc = "G://jf2.txt";
String dst = "hdfs://hadoop/use/jf2.txt";

InputStream in = new BufferedInputStream(new FileInputStream(locaSrc));

Configuration conf = new Configuration();
FileSystem fs = FileSystem.get(URI.create(dst), conf);
OutputStream out = fs.create(new Path(dst), new Progressable(){
public void progress(){
System.out.println("*");
}});

IOUtils.copyBytes(in, out, 4096, true);
}

}
复制代码

报错信息为： java.io.FileNotFoundException: G:/jf2.txt
请帮我看看，谢了。

楼主路径有误

hdfs路径
采用下面的方式：

String dst = "hdfs://hadoop/use/jf2.txt";

修改为：
String dst = "hdfs://hadoop：9000/use/jf2.txt";
或则
String dst = "hdfs://hadoop：8020/use/jf2.txt";
根据自己的配置来确定

磁盘路径：

String locaSrc = "G://jf2.txt";
修改为
String locaSrc = "G:/jf2.txt";
