5. jar包下载地址：hadoop-hdfs-2.0.1-alpha.jar下载地址(官方地址+国内镜像地址).txt
6. 源码下载地址：hadoop-hdfs-2.0.1-alpha-sources.jar下载地址(官方地址+国内镜像地址).txt

使用方法

1. 解压 hadoop-hdfs-2.0.1-alpha.jar中文-英文对照文档.zip，找到 解压后的文件夹>文档>index.html，双击index.html即可用浏览器打开查看。
2. 为了防止解压后路径太长导致浏览器无法打开，推荐在解压时选择“解压到当前文件夹”（放心，自带文件夹，文件不会散落一地）。
3. 有时，一套Java组件会有多个jar，所以在下载前，请仔细阅读本篇描述，以确保这就是你需要的文件。
