All of Mahout's clustering algos can be run in both MR and non-MR mode. By default its the MR mode that's executed unless the user chooses the non-MR mode by specifiying '-xm sequential' while invoking the driver.

So KMeans could be run in both map-reduce and non-mapreduce version and the decision will be made in driver, yes?
