Eclipse 添加 Hadoop 源代码包
Maven 仓库中没有 Hadoop 的源代码包，网络上也找不到可以直接用的，于是在官网下载整个Hadoop-1.2.1 包，提取出相应的源代码，打包后丢给 Eclipse ，仍然无法显示（奇怪，）。
解决步骤：
1，Eclipse 新建 Maven 项目，groupId 随意（建议不要为 org.apache.hadoop），artifactId 为 hadoop-core， 版本 1.2.1， package 为 jar
2，把Hadoop 源码放入 src/main/java 中
3，编辑pom.xml，引入依赖（详见下文）
4，编辑pom.xml，添加相应插件（javaDoc 和 source)
5，mvn install
6，更新相关项目对Hadoop 的引用
7，发布时记得改回来：）
抛砖引玉，如果有更好的解决麻烦告知，先谢过。
