             Summary: ProbabilisticClassificationModel.normalizeToProbabilitiesInPlace should return probabilities when given all-0 vector
                 Key: SPARK-18062
                 URL: https://issues.apache.org/jira/browse/SPARK-18062
             Project: Spark
          Issue Type: Improvement
          Components: ML
            Reporter: Joseph K. Bradley
            Priority: Trivial


{{ProbabilisticClassificationModel.normalizeToProbabilitiesInPlace}} returns a vector of all-0 when given a rawPrediction vector of all-0.  It should return a valid probability vector with the uniform distribution.

Note: This will be a *behavior change* but it should be very minor and affect few if any users.  But we should note it in release notes.
