This is not an HBase or Hadoop requirement... this is how Java works when pointing the classpath to jars.

That seemed to get rid of the ClassNotFoundException. I was following the instructions on the link you pointed out. However I am not sure why the jar files need to be explicitly listed. As far as I see, there are no instructions regarding the classpath on that link.
