Subject [jira] [Commented] (SPARK-15920) Using map on DataFrame
Date Thu, 01 Sep 2016 07:02:20 GMT


Sean Owen commented on SPARK-15920:

It was closed because it's a question, and that should go on the mailing list. JIRA is for
discussion of concrete changes in the source code.
You can call .map on a DataFrame anyway, and get a Dataset of the result, so the premise isn't
true. Well, at least I know that's the case for Scala.

> In Spark 1.6 there was a method {{}} as an alias to {{}}.
In spark 2.0 this functionality no longer exists.
> Is there a preferred way of doing map on a DataFrame without explicitly calling {{}}?
Maybe this functionality should be kept, just for backward compatibility purpose?
