----------------------------------
Summary: 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.
