Hi, Just came across this while looking at the docs on how to use Spark’s Kmeans clustering.
Note: This appears to be true in both 2.1 and 2.2 documentation. The overview page: https://spark.apache.org/docs/2.1.0/mllib-clustering.html#k-means Here’ the example contains the following line: val clusters = KMeans.train(parsedData, numClusters, numIterations) I was trying to get more information on the train() method. So I checked out the KMeans Scala API: https://spark.apache.org/docs/2.1.0/api/scala/index.html#org.apache.spark.mllib.clustering.KMeans The issue is that I couldn’t find the train method… So I thought I was slowly losing my mind. I checked out the entire API page… could not find any API docs which describe the method train(). I ended up looking at the source code and found the method in the scala source code. (You can see the code here: https://github.com/apache/spark/blob/v2.1.0/mllib/src/main/scala/org/apache/spark/mllib/clustering/KMeans.scala ) So the method(s) exist, but not covered in the Scala API doc. How do you raise this as a ‘bug’ ? Thx -Mike
