以下代码实现将本地文件拷到HDFS集群中

package com.njupt.hadoop;
 


 import org.apache.hadoop.conf.Configuration;

 import org.apache.hadoop.fs.FileSystem;

 import org.apache.hadoop.fs.Path;



 public class CopyToHDFS {



public static void main(String[] args) throws Exception{




Configuration conf = new Configuration();

FileSystem fs = FileSystem.get(conf);

Path source = new Path("/home/hadoop/word.txt");

Path dst = new Path("/user/root/njupt/");

fs.copyFromLocalFile(source,dst);

}

 }
