You should run the clusterdump on /home/r9r/seqTest/seqKmeans/clusters-1-final/part-xxxxx to see the points that are in the cluster. But u need a dictionary for that which wouldn't be available if the vectors were generated from CSV.
So one way to generate a dictionary for a CSV and verify the clustering output would be to go through the below process :- 1. Convert CSV file to a lucene index (see http://glaforge.appspot.com/article/lucene-s-fun for sample code). 2. Run the lucene index from (1) through Mahout's lucene2seq utility - this converts the lucene indexes into sequencefiles 3. Run the output of (2) thru seq2sparse - this should generate tf-idf vectors, dictionary, tf-vectors, wordcounts 4. Run the output of (3) thru KMeans Driver. Please give this a try.

I am using Mahout 0.9 on a local machine only. Below is the output from seqdumper, and I am not sure how to interpret it. Can anyone help?

I can get it into a sequence file, but this is the output. Thanks, Ronald
