running mahout on Hadoop 2.0.0-cdh4.3.1

Hi All,

I am used to running mahout (mahout-core-0.9-SNAPSHOT-job.jar) in the
Apache Hadoop environment, however, we had to switch to Cloudera
distribution.

When I try to run the item based collaborative filtering job
(org.apache.mahout.cf.taste.hadoop.item.RecommenderJob) in the Cloudera
distribution, I get the following error,

Exception in thread "main" java.lang.IncompatibleClassChangeError: Found
interface org.apache.hadoop.mapreduce.JobContext, but class was expected

Is there a way to run Mahout in the Cloudera environment? I mean, a
download specific to Cloudera distribution of Hadoop?

Thanks in advance,
