--------------------------------------
I'm not proceeding with the PR.
Fyi, you may find an implementation of this feature and all the others that I
suggested here:

> Add KMeans MiniBatch clustering algorithm to MLlib

> Key: SPARK-2308

> Mini-batch is a version of KMeans that uses a randomly-sampled subset of the
> data points in each iteration instead of the full set of data points,
> improving performance (and in some cases, accuracy). The mini-batch version
> is compatible with the KMeans|| initialization algorithm currently
> implemented in MLlib.
> I suggest adding KMeans Mini-batch as an alternative.
> I'd like this to be assigned to me.
