------------------------------------------
Here's what I'm getting after running cluster-reuters.sh kmeans with and
without the --namedVector flag.
$ mahout seqdumper -i
/tmp/mahout-work-akm/reuters-kmeans/clusters-2-final/part-r-00000
MAHOUT_LOCAL is set, so we don't add HADOOP_CONF_DIR to classpath.

> When clustering non-named vectors there are no vector ids in clusteredPoints
> so the other values there, cluster id, vector values, distance-squared, pdf,
> cannot be tied to any known vector.
