How to build and install the plug-in

To build the Eclipse plug-in, you need the Hadoop source files and a working Eclipse environment (version 3.3+). When compiling Hadoop, the Eclipse plug-in will be built if it founds the Eclipse environment path in the ant property "eclipse.home". The build framework looks for this property in ${hadoop-src-root}/src/contrib/eclipse-plugin/build.properties and in $HOME/eclipse-plugin.build.properties.

A typical $HOME/eclipse-plugin.build.properties file would contain the following entry: eclipse.home=/path/to/eclipse

Then the plug-in should be built when compiling Hadoop: ant clean package (from the ${hadoop-src-root} directory), which will produce {hadoop-src-root}/build/contrib/eclipse-plugin/hadoop-${version}-eclipse-plugin.jar
To install the generated plug-in in your Eclipse environment, remove first all previous versions of the plug-in from your Eclipse environment and copy the hadoop-${version}-eclipse-plugin.jar file generated as described above in your ${eclipse.home}/plugins/ directory. When you restart Eclipse, the Map/Reduce perspective should be available.
