Hadoop2.5 Eclipse插件制作、连接集群视频、及hadoop-eclipse-plugin-2.5.0插件下载
问题导读1.hadoop-eclipse-plugin源码如何下载？
2.插件编译需要哪些准备？
3.使用什么命令可以编译Eclipse插件？

Hadoop2.5 Eclipse插件安装视频

制作过程：
1.首先从git下载源码
下载地址：
https://github.com/winghc/hadoop2x-eclipse-plugin百度网盘下载：
链接：http://pan.baidu.com/s/1o6DMY4U 密码：y95i
下载之后，我们会看到下面文件夹
对于像安装git的用户，可以查看下面帖子
软件版本控制-在Windows中使用Git视频介绍
win7安装 git软件下载以及遇到的问题解决解决方法
2.win7编译
2.1编译准备
win7的编译首先需要安装jdk、ant、Eclipse
同样window也可以进行编译，环境如下图所示这里的
Eclipse的版本：
Version: 3.9.1.201308190730
Build id: 3.9.0.201308190730
也就是版本
Version: 3.9.1
Eclipse下载地址：链接：http://pan.baidu.com/s/1dDeT6UH 密码：tjdk
Eclipse的安装
Eclipse安装很重要，而且版本很重要，最好能版本一致，因为如果你在Linux制作的插件，只能用于Linux，windows插件只能用于windows，具体的Eclipse版本也尽可能一致，否则会遇到各种问题
2.2编译
aboutyun@master:~/hadoop2x-eclipse-plugin/src/contrib/eclipse-plugin$ ant jar -Dversion=2.5.0 -Declipse.home=/usr/eclipse -Dhadoop.home=/usr/hadoop
参数说明：
1.Dversion是你编译的版本，此版本为2.5.0
2.Declipse.home是Eclipse安装目录
3.Dhadoop.home是Hadoop安装目录
执行如下命令：
E:\hadoop2x-eclipse-plugin\src\contrib\eclipse-plugin>ant jar -Dversion=2.5.0 -D
eclipse.home=E:\eclipseIDE -Dhadoop.home=E:\bianyi\hadoop-2.2.0
上面Hadoop home需要说明的是，这里并不是使用的Hadoop2.5.0，经过各种验证，Dhadoop.home如果使用的是Hadoop2.5是非常痛苦的，需要各种修改，而且不一定能改正确。那么为什么Hadoop home是Hadoop2.2版本的也可以连接Hadoop2.5，这个需要了解内部原理了，感兴趣的同学，可以研究下。
编译后插件位置
build/contrib/eclipse-plugin目录下产生一个hadoop-eclipse-plugin-2.5.0.jar文件
下面附上在win7下，Eclipse版本为3.9.1的插件

然后尝试连接集群：
首先确认集群版本：
1.把插件放入plugins文件夹
然后打开win7下Eclipse，将hadoop-eclipse-plugin-2.5.0.jar插件放到Eclipse安装目录的plugins文件夹下，我这里的路径是E:\eclipseIDE\plugins
其实放到这里面已经完成大部分了。
2.重启Eclipse
通过window-》preference 找到下图所示，选择Hadoop安装目录
3.创建New hadoop location
通过下面操作，单击other
弹出show view对话框，然后单击map/reduce location
看到小象，如下图
右键New hadoop location
4.配置New hadoop location
5.查看效果
配置完毕，查看效果

问题总结：
插件的制作过程还是比较复杂的，原先使用的是Hadoop2.5版本，编译成功了，不能创建New Hadoop location查看log下面问题

网上有很多这方面的资料，尝试，但是还是未能解决。
使用Hadoop2.5作为编译目录，遇到下面问题：

经过多次修改未果，由于Hadoop Eclipse插件源码使用的是Hadoop2.2所以，就尝试用是Hadoop2.2作为Hadoop home，竟然编译成功了。
{:soso_e179:}{:soso_e179:}{:soso_e179:} 求下载，好 东西
谢谢楼主分享。 好难啊，要慢慢消化 值得试一下
很好很好，辛苦啦 希望这个版本的 hadoop插件是稳定的插件 谢谢版主分享 {:soso_e102:}来收货的~
