Hi, The plugin that comes with default hadoop folder is outdated.. it does not work well. usually...
You need to be very specific for which version of eclipse. Not all eclipse version are compatible with the hadoop plugin. Here we are using Eclipse SDK Helios 3.6.2. You can download it from here – http://www.eclipse.org/downloads/download.php?file=/eclipse/downloads/drops/R-3.6.2-201102101200/eclipse-SDK-3.6.2-linux-gtk.tar.gz To run Hadoop Map Reduce jobs on eclipse we need to install a plugin. The plugin can be downloaded from http://wiki.apache.org/hadoop/EclipsePlugIn. Open the JIRA MAPREDUCE-1280 link. Download hadoop-eclipse-plugin-0.20.3-SNAPSHOT.jar file put it in the <Eclipse_main_folder>/dropins folder. To run eclipse, go to the eclipse installation directory and run ” ./eclipse –clean” P.S .... This thing is tested on hadoop 0.20.2... I am not sure about the latest stable build.
