问题导读：
1.如何通过官网src包，获取hadoop的全部代码
2.通过什么样的操作，可以查看hadoop某个函数或则类的实现？
3.maven的作用是什么？






我们如果想搞开发，研究源码对我们的帮助很大。不明白原理就如同黑盒子，遇到问题，我们也摸不着思路。所以这里交给大家
一.如何获取源码
二.如何关联源码

一.如何获取源码

1.下载hadoop的maven程序包

（1）官网下载
这里我们先从官网上下载maven包hadoop-2.4.0-src.tar.gz。
官网下载地址

对于不知道怎么去官网下载，可以查看：新手指导：hadoop官网介绍及如何下载hadoop（2.4）各个版本与查看hadoop API介绍

（2）网盘下载
也可以从网盘下载：
http://pan.baidu.com/s/1kToPuGB

2.通过maven获取源码
获取源码的方式有两种，一种是通过命令行的方式，一种是通过eclipse。这里主要讲通过命令的方式

通过命令的方式获取源码：
1.解压包

解压包的时候遇到了下面问题。不过不用管，我们继续往下走

2.通过maven获取源码

这里需要说明的是，在使用maven的时候，需要先安装jdk，protoc ，如果没有安装可以参考win7如何安装maven、安装protoc

（1）进入hadoop-2.4.0-src\hadoop-maven-plugins，运行mvn install
  1. D:\hadoop2\hadoop-2.4.0-src\hadoop-maven-plugins>mvn install
复制代码

这时候，我们已经把源码给下载下来了。这时候，我们会看到文件会明显增大。

出现这个错误的原因：命令的执行路径不正确。
正确执行命令的方式
D:\hadoop2\hadoop-2.4.0-src\hadoop-maven-plugins>mvn install

mvn eclipse:eclipse -DskipTests （是在D:\hadoop2\hadoop-2.4.0-src路径下）

虽然你正确安装了，但是还是没有返回版本，所以你安装的还是有问题

你好：我使用的是win764位系统操作的，按照这个帖子操作的。http://www.aboutyun.com/forum.php?mod=viewthread&tid=8212&highlight=protoc，报同样的错误protoc --version' did not return a version -> [Help 1]，怎样确定protoc是正确安装了。安装过程中没有遇到使用pom.xml。
