Mahout v0.9 is not working with 2.2.0-cdh5.0.0-beta-1

Hi

Does Mahout v0.9 supports Cloudera Hadoop v5 (2.2.0-cdh5.0.0-beta-1)?
I have managed to installed and run all test cases under the Mahout v0.9 without any issue.
Please see below for the evident of the test cases.
However I have no success to run the example from http://girlincomputerscience.blogspot.com.au/2010/11/apache-mahout.html and got the following errors.
Note: I have set the CLASSPATH to point to all of Mahout's jar files.
