2.下载源码
https://github.com/winghc/hadoop2x-eclipse-plugin.git
3.编译
进入到hadoop2x-eclipse-plugin-master\src\contrib\eclipse-plugin目录执行如下命令：
ant jar -Dversion=2.6.0 -Declipse.home=E:\eclipse -Dhadoop.home=C:\hadoop-2.6.0
在目录hadoop2x-eclipse-plugin-master\build\contrib\eclipse-plugin下即可看到生成的插件hadoop-eclipse-plugin-2.6.0.jar
4.将hadoop-eclipse-plugin-2.6.0.jar插件拷贝到Eclipse安装目录的plugins文件夹下，启动Eclipse.在Window→Show View→Other下可以看到MapReduce Tools项,然后打开,右键New hadoop location，然后配置hadoop location项即可.
