小编给大家分享一下如何编译hadoop2.x的eclipse插件，相信大部分人都还不怎么了解，因此分享这篇文章给大家参考一下，希望大家阅读完这篇文章后大有收获，下面让我们一起去了解一下吧！
注意：以下操作基于Hadoop-2.4.1，Eclipse Luna，Win7 64位
1、下载插件源码包
https://github.com/winghc/hadoop2x-eclipse-plugin
2、新建eclipse java工程，将压缩包中以下目录的内容复制到project中（只是放到eclipse里边看而已，并不使用eclipse编译）
hadoop2x-eclipse-plugin-master.zip\hadoop2x-eclipse-plugin-master\src\contrib\eclipse-plugin
3、修改build.xml如下
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
