[jira] [Created] (SPARK-8674) 2-sample, 2-sided Kolmogorov Smirnov Test Implementation

Jose Cambronero created SPARK-8674:
--------------------------------------

             Summary: 2-sample, 2-sided Kolmogorov Smirnov Test Implementation
                 Key: SPARK-8674
                 URL: https://issues.apache.org/jira/browse/SPARK-8674
             Project: Spark
          Issue Type: New Feature
          Components: MLlib
            Reporter: Jose Cambronero
            Priority: Minor


We added functionality to calculate a 2-sample, 2-sided Kolmogorov Smirnov test for 2 RDD[Double]. The calculation provides a test for the null hypothesis that both samples come from the same probability distribution. The implementation seeks to minimize the shuffles necessary.
