RJ Nowling commented on SPARK-2430:
-----------------------------------

Hi Yu,

The community had suggested looking into scikit-learn's API so that is a good 
idea.

I am hesitant to make backwards-incompatible API changes, however, until we 
know the new API will be stable for a long time.  I think it would be best to 
implement a few more clustering algorithms to get a clear idea of what is 
similar vs different before making a new API.  May I suggest you work on 
SPARK-2966 / SPARK-2429 first?

> Recently, there has been a chorus of voices on the mailing lists about adding 
> new clustering algorithms to MLlib.  To support these additions, we should 
> develop a common framework and API to reduce code duplication and keep the 
> APIs consistent.
> At the same time, we can also expand the current API to incorporate requested 
> features such as arbitrary distance metrics or pre-computed distance matrices.
