 1.载
  载winghc/hadoop2x-eclipse-plugin 压缩包
  2.提取
  提取本路径(C:\hadoop2x-eclipse-plugin)
  3.搭建
  命令行窗口打'\src\contrib\eclipse-plugin'
  C:\>cd C:\hadoop2x-eclipse-plugin\src\contrib\eclipse-plugin
  运行ANT搭建
  C:\hadoop2x-eclipse-plugin\src\contrib\eclipse-plugin>ant jar -Dversion=2.2.0 -Declipse.home=C:/IDE/sts-3.5.0 -Dhadoop.home=c:/hadoopBuildfile: C:\hadoop2x-eclipse-plugin\src\contrib\eclipse-plugin\build.xml

  注意:载ivy-2.1.0.jar需要网络连接
  4. 安装
  搭建功'\src\contrib\eclipse-plugin'.内'hadoop-eclipse-plugin-2.2.0.jar' 拷贝jar文件并其粘贴IDE插件所路径
  5. 配置
  Eclipse启状态重新启否则要启
  a. 进入Windows-->Open Perspective-->Other并选择Map/Reduce
  b. 点击New Hadoop location...(蓝色象图标)并定义Hadoop路径运行MapReduce应用程序点击Finish按钮
  Map/Reduce(V2) Master:
  Map/Reduce主节点址(任务追踪器)
  DFS Master:
  布式文件系统主节点址(名称节点)
  要解Port数量启Hadoop并浏览器打 localhost:8088/cluster点击Tools --> Configuration 并查找属性
  DFS Master
   fs.defaultFS hdfs://localhost:9000 core-site.xml
  Map/Reduce(V2) Master mapreduce.jobtracker.http.address 0.0.0.0:50030 mapred-default.xml

  c. 现我浏览Hadoop文件系统并使用GUI执行同文件/文件夹操作
  同我用向导(File --> New --> Other... --> Map/Reduce)轻松创建
