Hadoop中eclipse 插件的编译 笔记四
Hadoop中eclipse 插件的编译
修改
hadoop-0.20.2\src\contrib\eclipse-plugin\src\java\org\apache\hadoop\eclipse\launch\HadoopApplicationLaunchShortcut.java
注掉
//import org.eclipse.jdt.internal.debug.ui.launcher.JavaApplicationLaunchShortcut;
添加
import org.eclipse.jdt.debug.ui.launchConfigurations.JavaApplicationLaunchShortcut;
在修改 hadoop-0.20.2\src\contrib\build-contrib.xml
加入
<property name="version" value="0.20.2"/>
<property name="eclipse.home" location="D:/tools/eclipse"/>
将hadoop-0.20.2下的hadoop-0.20.2-core.jar包拷到eclipse的plugins目录下。
在修改 hadoop-0.20.2\src\contrib\eclipse-plugin\build.xml
<path id="eclipse-sdk-jars">
<fileset dir="${eclipse.home}/plugins/">
<!--添加-->
<include name="hadoop*.jar"/>
</fileset>
</path>
cd到hadoop-0.20.2\src\contrib\eclipse-plugin下使用ant 编译
编译成功后会在hadoop-0.20.2\build\contrib\eclipse-plugin下
生成hadoop-0.20.2-eclipse-plugin.jar
Hadoop执行eclipse中的代码
将编译生成的hadoop-0.20.2-eclipse-plugin.jar放到eclpipse的plugins目录下,打开eclipse会看到
在windows-->hadoop map/reduce中添加hadoop的安装目录
Windows--->show view--->mapreduce tools-->map/reduce locations
在map/reduce location中右健-->new hadoop location 设置如下
Location名称随意map/reduct master
与( mapred-site.xml和hdfs-site.xml)的配置相同
右击刷新
新建项目
File-->new--->project-->map/reduce project
