I have compiled from the source using "mvn install" as shown in this tutorial. My hadoop is
setup and works alright. 
I have alse tried "hadoop jar mahout-examples*..." still doesn't work. 
I guess I need to setup up CLASSPATH, but I just don't know how. Could you please help me
with this issue. Sorry, I am a newbie...
