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...
