注意：以下操作基于Hadoop-1.2.1，Eclipse Luna，Win7 64位
1、将hadoop eclipse插件的工程导入Eclipse。插件源码目录如下：
D:\Lab\lib\hadoop\hadoop-1.2.1\src\contrib\eclipse-plugin
2、配置工程依赖
3、准备ant的配置文件
D:\Lab\lib\hadoop\hadoop-1.2.1\src\contrib\build-contrib.xml
将以上build-contrib.xml拷贝到项目目录中，并修改文件内容。具体如下：
4、修改build.xml
5、修改MENIFEST.MF，在Bundule-ClassPath中增加一些依赖的jar。
Bundle-ClassPath: classes/,
D:/Lab/lib/hadoop/hadoop-1.2.1/lib/hadoop-core-1.2.1.jar,
D:/Lab/lib/hadoop/hadoop-1.2.1/lib/commons-cli-1.2.jar,
D:/Lab/lib/hadoop/hadoop-1.2.1/lib/commons-configuration-1.6.jar,
D:/Lab/lib/hadoop/hadoop-1.2.1/lib/commons-httpclient-3.0.1.jar,
D:/Lab/lib/hadoop/hadoop-1.2.1/lib/commons-lang-2.4.jar,
D:/Lab/lib/hadoop/hadoop-1.2.1/lib/jackson-core-asl-1.8.8.jar,
D:/Lab/lib/hadoop/hadoop-1.2.1/lib/jackson-mapper-asl-1.8.8.jar
5、增加Ant Builder。
6、编译
在Project菜单中Build Project
7、运行结果
