Hadoop 2.2.0 Eclipse插件 [英] Hadoop 2.2.0 Eclipse Plugin

问题描述

我已经在我的电脑上安装了hadoop-2.2.0（单节点cluser）和maven3.3.1。我想在eclipse中编写MapReduce代码。所以我的问题是：

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:

1. mapreduce和maven之间的关系是什么？


2. 在eclipse中调试代码？一个教程说，我应该首先在旧版本中安装一个hadoop eclipse插件，但是似乎没有新版本的hadoop-2.2.0插件。如何解决这个问题？

推荐答案

1. maven和hadoop之间没有直接的关系

1. There is no direct relationship between maven and hadoop

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可以从中央信息管理项目的构建，报告和文档。

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.

使用maven可以下载依赖项开发hadoop / mapreduce项目

And using maven you can download dependencies to develop hadoop/mapreduce project

没有用于2.2.0的eclipse插件，它是仍然处于开发阶段，但您可以尝试IntelliJ IDEA，这也是Java的一个不错的开发工具。

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.
