[jira] [Commented] (SPARK-11664) Add methods to get bisecting k-means cluster structure

Hi,

I need to retrieve the tree structure (created by the Bisecting Kmeans algorithm)

Was [~yuu.ishikawa@gmail.com]'s solution  released as part of any official Spark release?

Thanks!

> I think users want to visualize the result of bisecting k-means clustering as a dendrogram in order to confirm it. So it would be great to support method to get the cluster tree structure as an adjacency list, linkage matrix and so on.
