Sean Owen commented on SPARK-17694:
-----------------------------------
Here what do you mean that it succeeds? it's a lazy transformation so won't
fail-fast, but if it's an incorrect mapping, it can't succeed when evaluated at
all right?
> convert DataFrame to DataSet should check columns match
> -------------------------------------------------------
>
> Key: SPARK-17694
> URL: https://issues.apache.org/jira/browse/SPARK-17694
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 1.6.1, 1.6.2
> Reporter: Chenliang Xu
> Priority: Minor
>
> The {{as}} method, which converts a DataFrame to DataSet requires the user to
> ensure the columns are match. And it success even the columns do not match,
> and cause error at later steps.
> It would be better, to let {{as}} match the columns, and fail/warn when the
> match fails.
