Timo Walther closed FLINK-8379.
-------------------------------
Resolution: Implemented
Improved as part of FLIP-65.
> Improve type checking for DataView
> ----------------------------------
>
> Key: FLINK-8379
> URL: https://issues.apache.org/jira/browse/FLINK-8379
> Project: Flink
> Issue Type: Improvement
> Components: Table SQL / API
> Reporter: Timo Walther
> Priority: Minor
> Labels: auto-deprioritized-major
>
> At the moment an accumulator with no proper type information is a valid
> accumulator.
> {code}
> public static class CountDistinctAccum {
> public MapView<Tuple, Integer> map;
> public long count;
> }
> {code}
> I quickly looked into the code and it seems that MapView with type
> information for key and value can be null. We should add a null check at the
> correct position to inform the user about the non-existing type information.
> We should also add the type check added with FLINK-8139 for the key type of
> MapView.
