Can you elaborate on that? Not sure what "--method mapreduce" means.
Some details:
- I have a CSV file.
- I programmatically create namedVectors (a java program).
- I run the kmeansdriver which (I thought) submits a number of mapreduce jobs.
- The output is another sequence file, which I then turn back into CSV.
- All sequence files are stored locally.
Side note:
I am overriding the distance method.
I can which distance method via a config file.
I can run Euclidian, or my distance function.

Subject: Re: Kmeans runs successfully, but no map/reduce jobs
Do you need --method mapreduce passed in?
