Kmeans clustering options
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
RE: Kmeans clustering options
Only using a -Dmapred.reduce.tasks=n parameter. The explicit CLI argument was dropped in 0.4. Looks like the book has a typo. -Original Message- From: moving...@gmail.com [mailto:moving...@gmail.com] On Behalf Of Kate Ericson Sent: Wednesday, April 06, 2011 5:45 PM To: user@mahout.apache.org Subject: Kmeans clustering options 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.
