首先说明一下配置的环境
系统：Ubuntu14.0.4
IDE：eclipse 4.4.1
Hadoop：Hadoop 2.2.0
对于Hadoop的旧版本，可以直接复制 hadoop安装目录/contrib/eclipse-plugin/hadoop-0.20.203.0-eclipse-plugin.jar 到 eclipse安装目录/plugins/ 下（并没有亲自验证）。对于Hadoop2，需要上https://github.com/winghc/hadoop2x-eclipse-plugin下载插件的源码自己进行编译生成jar文件。开始为了方便，直接下载别人编译后的jar文件，复制到eclipse的plugins文件夹下，但是重启eclipse后，无法找到Open PersPective中找到Map/Reduce插件。于是猜测插件的编译需要依赖，进而决定自行编译。
下载插件的源码，上面有清楚的编译方式
How to build $cd src/contrib/eclipse-plugin $ant jar -Dversion=2.2.0 -Declipse.home=/opt/eclipse -Dhadoop.home=/usr/share/hadoop final jar will be genrated at directory $root/build/contrib/eclipse-plugin/hadoop-eclipse-plugin-2.2.0.jar
由上可知，需要指定hadoop和eclipse的home目录，一下是我首次编译的结果

ivy-resolve-common的位置可能会等待一段时间。之后将生成的hadoop-eclipse-plugin-2.2.0.jar拷贝到eclipse的plugins文件夹下，重启eclipse，看见Hdoop插件已经安装成功
上文记录自己的安装过程，如果有所遗漏或错误，不吝赐教
