Sean Owen 56d3a7eb83 [SPARK-18808][ML][MLLIB] ml.KMeansModel.transform is very inefficient ... ## What changes were proposed in this pull request? mllib.KMeansModel.clusterCentersWithNorm is a method than ends up being called every time `predict` is called on a single vector, which is bad news for now the ml.KMeansModel Transformer works, which necessarily transforms one vector at a time. This causes the model to just store the vectors with norms upfront. The extra norm should be small compared to the vectors. This would avoid this form of overhead on this and other code paths. ## How was this patch tested? Existing tests.
