丸趣 TV 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-plugin2、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-plugin3、修改 build.xml 如下
?xml version= 1.0 encoding= UTF-8 standalone= no ?
