+ == 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.
