KMeansModel only returns the cluster centroids.
To get the # of elements in each cluster, try calling kmeans.predict() on each
of the points in the data used to build the model.
See
There's a kMeansModel.clusterCenters() available if u r looking to get the
centers from KMeansModel.

Subject: K-Means final cluster centers
Hi,
I am trying to get the final cluster
Andrew, u would be better off using Mahout's RowSimilarityJob for what u r
trying to accomplish.
1. It does give u pair-wise distances 2. U can specify the Distance measure
u r looking to use 3. There's the old MapReduce impl and the Spark DSL impl
per ur preference.

Here's the Streaming KMeans from Spark
1.2http://spark.apache.org/docs/latest/mllib-clustering.html#examples-1
Steaming KMeans still needs an initial 'k' to be specified, it then progresses
to come up with an optimal 'k' IIRC.

Mahout does have a kmeans which can be executed in mapreduce and iterative
modes.

I think Mahout uses FuzzyKmeans, which is different algorithm and it is not
iterative.
