[GitHub] spark issue #14640: [SPARK-17055] [MLLIB] add groupKFold to CrossValidator

[finleyb <gi...@git.apache.org>]

    @VinceShieh I was wondering if require in the groupKFold method of MLUtils should be a greater than or equal rather than less than or equal? I was testing this branch because I need this functionality for a ML task I am performing and I ran into the require. Thanks for implementing this!
