LGTM. Only one minor comment.
> No TypeInfo for Scala's Nothing type
> ------------------------------------
>
> Key: FLINK-2806
> URL: https://issues.apache.org/jira/browse/FLINK-2806
> Project: Flink
> Issue Type: Bug
> Components: Scala API
> Reporter: Gabor Gevay
> Assignee: Gabor Gevay
> Priority: Minor
>
> When writing some generic code, I encountered a situation where I needed a
> TypeInformation[Nothing]. Two problems prevent me from getting it:
> 1. TypeInformationGen.mkTypeInfo doesn't return a real
> TypeInformation[Nothing]. (It actually returns a casted null in that case.)
> 2. The line
> implicit def createTypeInformation[T]: TypeInformation[T] = macro
> TypeUtils.createTypeInfo[T]
> does not fire in some situations when it should, when T = Nothing. (I guess
> this is a compiler bug.)
> I will open a PR shortly.
