-------------------------------
> Improve error messages in AbstractDeserializationSchema for type extraction
> ---------------------------------------------------------------------------
>
> Key: FLINK-9198
> URL: https://issues.apache.org/jira/browse/FLINK-9198
> Project: Flink
> Issue Type: Improvement
> Affects Versions: 1.4.2
> Reporter: Stephan Ewen
> Assignee: Stephan Ewen
> Priority: Major
> Fix For: 1.5.0
>
>
> User feedback: When type extraction fails in the
> {{AbstractDeserializationSchema}}, the error message does not explain fully
> how to fix this.
> I suggest to improve the error message and add some convenience constructors
> to directly pass TypeInformation when needed.
> We can also simplify the class a bit, because TypeInformation needs no longer
> be dropped during serialization.
