Kmeans clustering options

[Kate Ericson]

Hi all,

I just got the latest update to the first 6 chapters of Mahout In
Action, and it still says that '-r' is an option to k-means
clustering.  I'm working with 0.4, and I'm not seeing it as an option
off of -h.
I'm just looking for a sanity check - can you set the number of
reducers for k-means?

Thanks,

Kate

Only using a -Dmapred.reduce.tasks=n parameter. The explicit CLI argument was 
dropped in 0.4. Looks like the book has a typo.
