eclipse luna 安装 Hadoop 1.2.1 eclipse-plugin

　　博主最近学习Hadoop 1.2.1，从多个搜索引擎的搜索结果当中汇合得出本文Hadoop 1.2.1 Eclipse-plugin安装过程介绍，如果你是从网上下载hadoop-eclipse-plugin-1.2.1.jar放进eclipse的plugins目录后发现并未被成功加载时，可以尝试本文内的编译安装方法。

一、软件环境准备

JDK版本：jdk-6u45-windows-x64.exe

Hadoop版本：hadoop-1.2.1.tar.gz

IDE版本：eclipse-java-luna-SR1a-win32-x86_64.zip

ANT版本：apache-ant-1.9.4-bin.zip

操作系统：Windows 8.1 64bit

二、安装前期准备

JDK：安装过程忽略，请自行网上搜索安装资料。

Hadoop：将hadoop-1.2.1.tar.gz解压到D:\

eclipse：将eclipse-java-luna-SR1a-win32-x86_64.zip解压到D:\Program Files\

ANT：将apache-ant-1.9.4-bin.zip解压到D:\Program Files\

- 配置ANT环境变量 -

　　目前我是将环境变量配置到用户环境变量当中，当然你可以根据需要配置为系统环境变量。ant需要配置一个ANT_HOME和在Path中添加%ANT_HOME%\bin

　　　　1.ANT_HOME = D:\Program Files\apache-ant-1.9.4

　　　　2.Path 末尾添加 ;%ANT_HOME%\bin

　　　　3.打开命令行窗口输入ant按回车，如出现Buildfile等文字代表环境变量已设置正确，ant已可用

ant设置过程如下图示：

软件最终目录情况如下图示：

三、编译hadoop-eclipse-plugin-1.2.1

1.用文本编辑器打开D:\hadoop-1.2.1\src\contrib\eclipse-plugin\build.properties设置eclipse.home及version

output.. = bin/
bin.includes = META-INF/,\
               plugin.xml,\
               resources/,\
               classes/,\
               classes/,\
               lib/

2.修改D:\hadoop-1.2.1\src\contrib\eclipse-plugin\build.xml

      <fileset dir="${root}" includes="resources/ plugin.xml"/>

3.修改D:\hadoop-1.2.1\src\contrib\eclipse-plugin\META-INF\MANIFEST.MF

Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: MapReduce Tools for Eclipse
Bundle-SymbolicName: org.apache.hadoop.eclipse;singleton:=true
Bundle-Version: 0.18
Bundle-Activator: org.apache.hadoop.eclipse.Activator
Bundle-Localization: plugin
Require-Bundle: org.eclipse.ui,
 org.eclipse.core.runtime,
 org.eclipse.jdt.launching,
 org.eclipse.debug.core,
 org.eclipse.jdt,
 org.eclipse.jdt.core,
 org.eclipse.core.resources,
 org.eclipse.ui.ide,

 pper-asl-1.8.8.jar
Bundle-Vendor: Apache Hadoop

4.利用ant编译hadoop-eclipse-plugin-1.2.1.jar

　　打开cmd.exe，用cd命令定位到D:\hadoop-1.2.1\src\contrib\eclipse-plugin后执行ant回车

>cd /d D:\hadoop-1.2.1\src\contrib\eclipse-plugin
>ant >>d:\eclipse-plugin-build.log

　　完成后打开d:\eclipse-plugin-build.log在文件结尾看到BUILD SUCCESSFUL字样则代表jar包编译完成。这里需要注意的是设置build.properties中的eclipse.home为你eclipse的存放目录位置。

四、安装hadoop-eclipse-plugin-1.2.1.jar

　　安装过程就稍微简单多了，将本机上D:\hadoop-1.2.1\build\contrib\eclipse-plugin\hadoop-eclipse-plugin-1.2.1.jar拷贝至D:\Program Files\eclipse\plugins\目录后启动Eclipse即可。

最终效果如下图示：

参考：

　　1.JDK1.6安装与环境变量设置详细图解

　　2.ant安装、环境变量配置及验证

　　3.Build hadoop-eclipse-plugin-1.2.1.jar
