1、Hadoop-2.6.0环境下配置Eclipse开发环境：1.下载(eclipse-standard-kepler-SRl-linux-gtk.tar),假设解压到/home/u/eclipse在/etc/profile中设置ant路径：exportECLIPSE_HOME=/home/u/eclipseexportPATH=.:$ECLIPSE_HOME:$PATH2.下载ant安装包(apacheFnt・1.9.2・bin.tar.gz),假设解压至lj/home/u/apache-ant-l.9.2

2、Fl录，在/etc/profile中设置ant路径：exportANT_HOME=/home/u/apache-ant-1.9.2exportPATH=.:$ANT_HOME/bin:$PATH3.下载maven安装包(apache-maven-3.2.1-bin.tar.gz),假设解压到/home/u/apache-maven-3.2.1口录，在在/etc/profile屮设置maven路径：exportMAVEN_HOME=/home/u/apache-maven-3.2.1exportPATH=.

3、:$MAVEN_HOMEE/bin:$PATH4.复制hadoop2.6-eclipse-plugin.zip解压到/home/u,cd/home/u/hadoop2.6-eclipse-plugin/src/contrib/eclipse-pluginantjar-Dversion=2.6.0-Dhadoop.version=2.6.0・Declipse.home=/home/u/eclipse・Dhadoop.home=/home/u/Hadoop-2.6.0编译成功后我们可以在以下目录获得hadoo

4、p-eclipse-plugin-2.6.0.jar插件。${hadoop2x-eclipse-plugin}/build/contrib/eclipse-plugin/hadoop-eclipse-plugin-2.6.0.jar5.将hadoop-eclipse-plugin-2.6.0.jar拷贝至/home/u/eclipse/pluginsF,重启eclipse.可在Preference里看到HadoopMap/Reduce插件牛.效。❽O©CVSRepositoryExploring・Ecli
