dardelet 4d6d8192c8 [SPARK-21268][MLLIB] Move center calculations to a distributed map in KMeans ... ## What changes were proposed in this pull request? The scal() and creation of newCenter vector is done in the driver, after a collectAsMap operation while it could be done in the distributed RDD. This PR moves this code before the collectAsMap for more efficiency ## How was this patch tested? This was tested manually by running the KMeansExample and verifying that the new code ran without error and gave same output as before.
