进入%Hadoop_HOME%\src\contrib\
编辑build-contrib.xml
加入
<property name="version" value="1.0.3"/>
<property name="eclipse.home" location="D:/soft/eclipse-jee-indigo-SR1-win32/eclipse"/>
将%Hadoop_HOME%下的jar包拷到eclipse所在目录的plugins目录下,比如hadoop-core-*.jar
进入%Hadoop_HOME%\src\contrib\eclipse-plugin
编辑build.xml
在
<path id="eclipse-sdk-jars">
<fileset dir="${eclipse.home}/plugins/">
</fileset>
</path>
中加入
<include name="hadoop*.jar"/>
将compile模块中
deprecation="${javac.deprecation}
去掉。
打开CMD在%Hadoop_HOME%\src\contrib\eclipse-plugin下使用ant
这时开始编译。
jar: [echo] version:1.0.3 [copy] Copying 1 file to D:\hadoop-1.0.3\build\contrib\eclipse-plugin\lib [copy] Copying D:\hadoop-1.0.3\build\ivy\lib\Hadoop\common\commons-cli-1.2. jar to D:\hadoop-1.0.3\build\contrib\eclipse-plugin\lib\commons-cli-1.2.jar [jar] Building jar: D:\hadoop-1.0.3\build\contrib\eclipse-plugin\hadoop-ec lipse-plugin-1.0.3.jar BUILD SUCCESSFUL Total time: 2 seconds
注意,在编译的过程中可能会报错,主要出在jar时的copy问题上,把commons-cli-1.2.jar与拷到 %HADOOP_HOME%\build\ivy\lib\Hadoop\common\下,将hadoop-core-1.0.3.jar拷到%HADOOP_HOME%\build下即可。
编译成功后,会在 %Hadoop_Home%\build\contrib\eclipse-plugin\下生成hadoop-eclipse-plugin-1.0.3.jar。将其拷到eclipse所在目录的plugins目录下。重新打开eclipse
选择window-open perspective-other,会看到
选择Map/Reduce
选择window-show view-other
选择Map/Reduce Locaions
到这eclipse的hadoop插件就编译成功了。
附上我自己编译后的插件:hadoop-eclipse-plugin 1.0.3 eclipse4.2中可以使用
