----------------------------------
[~lian cheng] We can resolve this one, right?
> Don't assign default value for non-nullable columns of a Dataset
> ----------------------------------------------------------------

> Key: SPARK-12323
> URL: https://issues.apache.org/jira/browse/SPARK-12323
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 1.6.0, 2.0.0
> Reporter: Cheng Lian
> Assignee: Cheng Lian
>
> For a field of a Dataset, if it's specified as non-nullable in the schema of
> the Dataset, we shouldn't assign default value for it if input data contain
> null. Instead, a runtime exception with nice error message should be thrown,
> and ask the user to use {{Option}} or nullable types (e.g.,
> {{java.lang.Integer}} instead of {{scala.Int}}).
