Predict clusters from data using Spark MLlib KMeans

I have generated my cluster centers from features of my data say 'Kmeans.data.txt' as you find in

https://github.com/apache/spark/blob/master/data/mllib/kmeans_data.txt

This was performed using KMeans in Spark MLib.

clusters.clusterCenters.foreach(println)

Any idea how to predict the clusters derived from this data?
