Hie,
I am quite new to the mahout. I have successfully installed it and
want to run kmeans my own parameters and files. when i run kmeans with
following parameters i get the error ('clusters' is a fake folder)
$MAHOUT_HOME/bin/mahout kmeans -i testdata/tfidf-vectors/ -o output2 -c
clusters -dm org.apache.mahout.common.distance.CosineDistanceMeasure -x 10
-ow -cd .1 -k 5 --clustering -cl
Running on hadoop, using Downloads/hadoop-1.2.1/bin/hadoop and
HADOOP_CONF_DIR=
MAHOUT-JOB:
