-----------------------------------

             Summary: Improve error message for TypyInformation and TypeHint with generics
                 Key: FLINK-9197
                 URL: https://issues.apache.org/jira/browse/FLINK-9197
             Project: Flink
          Issue Type: Improvement
          Components: Core
    Affects Versions: 1.4.2
            Reporter: Stephan Ewen
            Assignee: Stephan Ewen
             Fix For: 1.5.0


User feedback: When using a {{TypeHint}} with a generic type variable, the error message could be better. Similarly, when using {{TypeInformation.of(Tuple2.class)}}, the error message should refer the user to the TypeHint method.
