[jira] [Created] (SPARK-15947) Make pipeline components backward compatible with old vector columns in Scala/Java

Xiangrui Meng created SPARK-15947:
-------------------------------------

             Summary: Make pipeline components backward compatible with old vector columns in Scala/Java
                 Key: SPARK-15947
                 URL: https://issues.apache.org/jira/browse/SPARK-15947
             Project: Spark
          Issue Type: Sub-task
          Components: ML, MLlib
    Affects Versions: 2.0.0
            Reporter: Xiangrui Meng


After SPARK-15945, we should make ALL pipeline components accept old vector columns as input and do the conversion automatically (probably with a warning message), in order to smooth the migration to 2.0.
