在windows下配置hadoop-eclipse插件，并连接虚拟机的hadoop集群
前提：本地环境java+ant
本编译使用eclipse3.6，一开始用的3.7一致报错，网上找了好久。。。。必须3.6

• 下载hadoop-1.1.2.tar.gz到本地目录
  
• 使用Git Bash（可模拟部分linux的命令）解压hadoo-1.1.2.tar.gz文件
  

Git下载路径：https://code.google.com/p/msysgit/downloads/list?q=full+installer+official+git

• 进入${hadoop.home}/src/contrib/eclipse-plugin目录写该build.xml文件
  

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<project default="jar" name="eclipse-plugin">
<property name="name" value="${ant.project.name}"/>
<property name="root" value="${basedir}"/>

manifest="${root}/META-INF/MANIFEST.MF">
<fileset dir="${build.dir}" includes="classes/ lib/"/>
<fileset dir="${root}" includes="resources/ plugin.xml"/>
</jar>
</target>
</project>

• 编辑META-INF/ MANIFEST.MF
  

添加如下
Eclipse-LazyStart: true
Bundle-ClassPath: classes/,lib/hadoop-core.jar,lib/commons-cli-1.2.jar,lib/commons-configuration-1.6.jar,lib/commons-httpclient-3.0.1.jar,lib/commons-lang-2.4.jar,lib/jackson-core-asl-1.8.8.jar,lib/jackson-mapper-asl-1.8.8.jar
Bundle-Vendor: Apache Hadoop
 

• Cmd命令行工具进入eclipse-plugin目录执行命令ant 编译
  
• 到${hadoop.home}/build/contrib/eclipse-plugin目录可以找到hadoop-eclipse-plugin-1.1.2.jar文件，拷贝到${eclipse.home}/plugins/
  
• 启动eclipse然后其他的配置方式网上都有了。
  

  注意：请把windows的用户名该为与hadoop集群同名的用户名如grid
