             Summary: QuantileDiscretizer should take random seed
                 Key: SPARK-11515
                 URL: https://issues.apache.org/jira/browse/SPARK-11515
             Project: Spark
          Issue Type: New Feature
          Components: ML
            Reporter: Joseph K. Bradley
            Priority: Minor


QuantileDiscretizer takes a random sample to select bins.  It currently does 
not specify a seed for the XORShiftRandom, but it should take a seed by 
extending the HasSeed Param.
