> Key: SPARK-14844
> URL: https://issues.apache.org/jira/browse/SPARK-14844
> Project: Spark
> Issue Type: Improvement
> Components: ML
> Affects Versions: 1.6.0, 1.6.1
> Reporter: Dominik Jastrzębski
>
> We need to add setFeaturesCol, setPredictionCol methods in org.apache.spark.ml.clustering.KMeansModel.
> This will allow to:
> * transform a DataFrame with different feature column name than in the DataFrame the model was fitted on.
> * create a prediction column with name other than the name that was set during model fitting.
