Djellel Eddine Difallah commented on MAHOUT-551:
------------------------------------------------
I have modified the synthetic control kmeans Job to include the -k option, and
is now the default execution mode with k= 6 (given the dataset).
However with user supplied arguments, one should always include -t1 -t2 because
the DefaultDreator makes them required even when using -k. Is that ok ?

> The provided example for Kmeans clustering using the synthetic control data
> asks for t1 and t2 measures because it runs the Canopy Driver to determine
> the initial clusters. Kmeans originally requires a K variable to generate
> random centers from the input data. I propose to add another example in the
> package which will serve for any space delimited numerical input to cluster
> with Kmeans in its original form and not using Canopy. The modification is
> quite simple and is mostly based on the synthetic control Job.
