Hadoop 2.2.0 Eclipse Plugin
提问by user2991640
I have installed hadoop-2.2.0 (single node cluser) and maven3.3.1 on my pc. I want to program MapReduce code in eclipse. So my questions are:
我已经在我的电脑上安装了 hadoop-2.2.0（单节点集群）和 maven3.3.1。我想在 eclipse 中编写 MapReduce 代码。所以我的问题是：
- What is the relationship between mapreduce and maven?
- How do I debug the code in eclipse? A tutorial says that I should first install a hadoop eclipse plugin in an old version, but it seems there isn't a plugin for the new version hadoop-2.2.0. How can I solve this?
- mapreduce 和 maven 是什么关系？
- 如何在eclipse中调试代码？一个教程说我应该先在旧版本中安装一个hadoop eclipse插件，但似乎没有新版本hadoop-2.2.0的插件。我该如何解决这个问题？

There is no direct relationship between maven and hadoop
Apache Maven is a software project management and comprehension tool. Based on the concept of a project object model (POM), Maven can manage a project's build, reporting and documentation from a central piece of information.
And using maven you can download dependencies to develop hadoop/mapreduce project
There is no eclipse plugin for 2.2.0, it's still in development stage but you can try IntelliJ IDEA, which is also a nice development tool for java.

maven和hadoop没有直接关系
Apache Maven 是一个软件项目管理和理解工具。基于项目对象模型 (POM) 的概念，Maven 可以从一条中央信息中管理项目的构建、报告和文档。
并且使用 maven 可以下载依赖项来开发 hadoop/mapreduce 项目
2.2.0没有eclipse插件，还在开发阶段，不过你可以试试IntelliJ IDEA，它也是一个不错的java开发工具。
