Hi Mahesh,
Thanks for your reply.
I am executing the Mahout api example - KMeans algorithm 
https://cwiki.apache.org/MAHOUT/clustering-of-synthetic-control-data.html
$MAHOUT_HOME/bin/mahout org.apache.mahout.clustering.syntheticcontrol.kmeans.Job

I am using the following VersionHadoop 1.0.1Mahout 0.7

Thanks,Anbu
