Seth Hendrickson updated SPARK-17163:
-------------------------------------
    Description: 
Before the 2.1 release, we should finalize the API for logistic regression. 
After SPARK-7159, we have both LogisticRegression and 
MultinomialLogisticRegression models. This may be confusing to users and, is a 
bit superfluous since MLOR can do basically all of what BLOR does. We should 
decide if it needs to be changed and implement those changes before 2.1

*Update*: Seems we have decided to merge the two estimators. I changed the 
title to reflect that.

        Summary: Merge MLOR into a single LOR interface  (was: Decide on 
unified multinomial and binary logistic regression interfaces)
