如何編譯hadoop2.4.1插件

小編給大家分享一下如何編譯hadoop2.4.1插件，相信大部分人都還不怎么了解，因此分享這篇文章給大家參考一下，希望大家閱讀完這篇文章后大有收獲，下面讓我們一起去了解一下吧！

操作于 win7 32位  Eclipse 4.1  Kepler 

①下載插件源碼包

https://github.com/winghc/hadoop2x-eclipse-plugin

點擊右側download下載

解壓，打開解壓目錄“ xxxx\hadoop2x-eclipse-plugin-master\src\contrib”

②新建一個java項目

將contrib下的eclipse-plugin里面的內容拷貝到java項目下實際上只要拷貝5個就好。

META-INF
resources
src
build.properties
plugin.xml

拷貝完成了。那么問題來了：

全是紅叉叉。。。(個人有很多紅叉叉網上資料全都沒有描述，解決后記錄下。)

好像有個包名錯了。。這個自己改吧- -不解釋；

缺少一些jar包，(不小心放了漢化包。。以中文的描述吧問題不難，英文的相信你們對應的上)

缺少的第一部分jar包為"插件依賴項":右鍵項目->構建路徑->配置構建路徑->然后添加庫->插件依賴項 下一步完成！

還有錯。。。少jar包。

這個jar包不截圖了大概就是少org.apache.hadoop.fs 類似的

大家都說去源碼包lib下找到jar包全部引入就好。。。可是我的lib下面沒有啊- -真的沒有啊啊啊啊。。。

所以不要糾結了- -(認真你就輸了,這個錯誤可以繼續后續編譯,編譯完成了,jar包就來了所以不要在這些jar包上找方法了)。

③修改build.xml文件

<?xml version="1.0" encoding="UTF-8" standalone="no"?>

修改前5項：

jdk.home指定編譯時用的jdk，

hadoop和eclipse版本號是用來給jar起名字的，

hadoop.home是hadoop安裝目錄，會從里面提取需要的文件，

eclipse.home是eclipse的安裝目錄，MyEclipse中是那個Common目錄。

everything is ok！ 右鍵build.xml文件Run AS Ant Build
