收集整理的這篇文章主要介紹了
编译hadoop的eclipse插件hadoop-eclipse-plugin-1.2.1.jar
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
1：下載后hadoop-1.1.2.tar.gz文件，里面包含源代碼，并解壓到E:\hadoop\hadoop-1.2.1
2：在eclipse導入工程，目錄選擇：E:\hadoop\hadoop-1.2.1\src\contrib\eclipse-plugin
3：在項目 MapReduceTools 中新建 lib 目錄，將 hadoop-1.2.1 下的 hadoop-core-1.2.1.jar，及其 lib 目錄下的 commons-cli-1.2.jar、commons-lang-2.4.jar、
commons-configuration-1.6.jar、jackson-mapper-asl-1.8.8.jar、jackson-core-asl-1.8.8.jar、commons-httpclient-3.0.1.jar 拷貝到該目錄。
4：修改項目的Libraries
5：修改build-contrib.xml
將E:\hadoop\hadoop-1.2.1\src\contrib目錄下的build-contrib.xml文件拷貝到項目目錄中，注意：build-contrib.xml文件以eclipse-plugin是在同一級目錄中，拷貝完成以后修改build-contrib.xml文件。修改的內容如下。
<property name="name" value="${ant.project.name}"/><property name="root" value="${basedir}"/><property name="version" value="1.2.1"/> <!--這行為新增的內容--><property name="hadoop.root" location="E:/hadoop/hadoop-1.2.1"/><!--這行為修改的內容--><property name="eclipse.home" location="E:/work/eclipse-jee-kepler-SR2-win32/eclipse" /><!--這行為修改的內容-->
6：修改build.xml
如果導入項目的時候選擇的是copy的話，需要E:\hadoop\hadoop-1.2.1\src\contrib\eclipse-plugin下的build.xml文件拷貝到項目目錄中，不是的話直接修改。
下面是完整的內容：

在Bundle-ClassPath添加下面的內容 Bundle-ClassPath: classes/,lib/hadoop-core.jar,lib/
8：Ant 編譯
a. 右鍵 MapReduceTools 工程，Properties—>Builders—>New—>Ant Builder
b. 修改New_Builder編輯界面中的內容
Name (見名知意): hadoop_Builder
Buildfile (build.xml的位置): 項目路徑下面\build.xml
3. 修改完成保存
4. 點擊Project—>Build Project進行生成
點擊Project—>Build Project開始進行生成，這時候我們會看到控制臺輸出一堆相關的編譯信息，編譯成功會看到在控制臺輸出 BUILD SUCCESSFUL 。編譯結果在 E:\hadoop\hadoop-1.2.1\build\contrib\eclipse-plugin目錄下。
安裝插件
安裝插件到eclipse的話就需要將 hadoop-eclipse-plugin-1.2.1.jar 放入 到eclipse的plugins 目錄下，重啟 eclipse即可。
