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