Hyukjin Kwon resolved SPARK-3220.
---------------------------------
Resolution: Incomplete
> K-Means clusterer should perform K-Means initialization in parallel
> -------------------------------------------------------------------
>
> Key: SPARK-3220
> URL: https://issues.apache.org/jira/browse/SPARK-3220
> Project: Spark
> Issue Type: Improvement
> Components: MLlib
> Reporter: Derrick Burns
> Priority: Major
> Labels: bulk-closed, clustering
>
> The LocalKMeans method should be replaced with a parallel implementation. As
> it stands now, it becomes a bottleneck for large data sets.
> I have implemented this functionality in my version of the clusterer.
> However, I see that there are hundreds of outstanding pull requests. If
> someone on the team wants to sponsor the pull request, I will create one.
> Otherwise, I will just maintain my own private fork of the clusterer.
