• Common

Getting Started

The Hadoop documentation includes the information you need to get started using Hadoop. Begin with the Single Node Setup which shows you how to set up a single-node Hadoop installation. Then move on to the Cluster Setup to learn how to set up a multi-node Hadoop installation.

Hadoop文档包含这些信息需要你去学习开始使用HADOOP，开始先学习单个节点安装，这个向你展示单个节点hadoop安装。再开始集群安装，学习如何安装多个节点的HADOOP安装。

MapReduce

The Hadoop MapReduce Documentation provides the information you need to get started writing MapReduce applications. Begin with the MapReduce Tutorial which shows you how to write MapReduce applications using Java. To write MapReduce applications in languages other than Java see Hadoop Streaming, a utility that allows you to create and run jobs with any executable as the mapper or reducer.

Hadoop MapReduce文档向你提供一些信息，你需要开始学习写MapReduce应用程序，从MapReduce教程开始，这部分展示如何使用java写MapReduce用用程序。如果要使用其他语言写MapReduce程式，需要看 Hadoop Streaming，一种实用工具允许你创建和允许工作，用任何可执行的程式，作为mapper 或 reducer

HDFS

The HDFS Documentation provides the information you need to get started using the Hadoop Distributed File System. Begin with the HDFS Users Guide to obtain an overview of the system and then move on to the HDFS Architecture Guide for more detailed information.

Common

The Common Documentation describes the common utilities and libraries that support the other Hadoop subprojects.

If you have more questions about Hadoop, you can ask on the Mailing Lists or browse the Mailing List Archives.

这部分公共文档描述一个公共工具和库文件，它们支持HADOOP另外的子项目，你若有更多问题关于HADOOP，你可以通过邮件列表获取信息。
