Apache Spark reassigned SPARK-14500:
------------------------------------
Assignee: Apache Spark (was: Xiangrui Meng)
> Accept Dataset[_] instead of DataFrame in MLlib APIs
> ----------------------------------------------------
>
> Key: SPARK-14500
> URL: https://issues.apache.org/jira/browse/SPARK-14500
> Project: Spark
> Issue Type: New Feature
> Components: ML
> Reporter: Xiangrui Meng
> Assignee: Apache Spark
>
> In Spark 2.0, `DataFrame` is an alias of `Dataset[Row]`. MLlib API actually
> works for other types of `Dataset`, so we should accept `Dataset[_]` instead.
> It maps to `Dataset<?>` in Java. This is a source compatible change.
