Hadoop学习之路（八）在eclispe上搭建Hadoop开发环境

一、添加插件

将hadoop-eclipse-plugin-2.7.5.jar放入eclipse的plugins文件夹中

package cn.study.hdfs;

import java.net.URI;

import org.apache.hadoop.conf.Configuration;
import org.apache.hadoop.fs.FileSystem;
import org.apache.hadoop.fs.Path;

public class TestHdfsDemo1 {

public static void main(String[] args) throws Exception {
Configuration conf = new Configuration();
FileSystem fs = FileSystem.get(new URI("hdfs://hadoop1:9000"),conf,"hadoop");
//System.out.println(fs instanceof DistributedFileSystem);//true

fs.copyFromLocalFile(new Path("D:/abc.txt"), new Path("/a/"));
fs.close();
}

}
