                 Key: SPARK-2309
                 URL: https://issues.apache.org/jira/browse/SPARK-2309
             Project: Spark
          Issue Type: New Feature
          Components: MLlib
            Reporter: DB Tsai


There is no multi-class classifier in mllib now. Logistic regression can be extended to multinomial one straightforwardly. 


The following formula will be implemented.
