hadoop 2.8.3 eclipse 插件

Windows Server 2012 R2 Standard
hadoop 2.8.3
eclipse-jee-mars-2-win32-x86_64

1. 从https://github.com/winghc/hadoop2x-eclipse-plugin下载源码到本地；
2. 下载ant。
3. 修改两个文件：
   3.1. \hadoop2x-eclipse-plugin-master\ivy\libraries.properties
   将里面的jar包版本改为hadoop对应的版本
   3.2. \hadoop2x-eclipse-plugin-master\src\contrib\eclipse-plugin\build.xml，修改jar包名称，我把命令行中的参数直接写在这个文件中了。
4. 命令行cd到目录hadoop2x-eclipse-plugin-master\src\contrib\eclipse-plugin，执行ant jar命令：
   
5. 将\hadoop2x-eclipse-plugin-master\build\contrib\eclipse-plugin\目录下的hadoop-eclipse-plugin-2.8.3.jar拷贝到\eclipse\plugin目录下；
6. 启动eclipse；会看到下面的图标：
   
7. 然后点击windows->show view->MapReduce Tools->Map/Reduce Locations。
   
8. 点击这个视图右上角的小象进行配置：
   
9. 启动hadoop，在命令行输入：hadoop fs -mkdir /Administrator
   （Adiministrator是我的用户名）
10. ok

刚开始编译不成功，根据错误提示，修改了libraries.properties和build.xml，编译成功。但放到eclipse（这时eclipse版本是oxygen）中可以显示，但遇到下面的错误（查看eclipse错误日志），

我感觉错误的意思是找不到hrace的jar包，但插件里面有这个包啊，不知道该怎么改。
如果您遇到这个问题，解决了，麻烦告诉我，谢谢！
应该是jar包不对，我直接改的插件包，从新编译下，然后这样启动eclipse：eclipse -clean -consolelog -debug，就可以了。

然后就换了eclipse的版本，用mars。mars遇到了另外一个问题：

!MESSAGE An internal error occurred during: "Map/Reduce location status updater".

    at org.eclipse.core.internal.jobs.Worker.run(Worker.java:55)

这个问题参考下面的方法可以解决，hadoop dfs -mkdir /Administrator
