Could you attach a test which can reproduce the problem?
> DataType to LogicalType conversion issue
> ----------------------------------------
>
> Key: FLINK-15574
> URL: https://issues.apache.org/jira/browse/FLINK-15574
> Project: Flink
> Issue Type: Improvement
> Components: Table SQL / Runtime
> Reporter: Benoit Hanotte
> Priority: Major
>
> We seem to be encountering an issue with the conversion from DataType to LogicalType with the Blink planner (full stacktrace below):
> {code}
> org.apache.flink.table.api.ValidationException: Type LEGACY(BasicArrayTypeInfo<String>) of table field 'my_array' does not match with type BasicArrayTypeInfo<String> of the field 'my_array' of the TableSource return type.
> {code}
> It seems there exists 2 paths to do the conversion from DataType to LogicalType:
> 1. TypeConversions.fromLegacyInfoToDataType():
> used for instance when calling TableSchema.fromTypeInformation().
> 2. LogicalTypeDataTypeConverter.fromDataTypeToLogicalType():
> Deprecated but still used in TableSourceUtil and many other places.
> These 2 code paths can return a different LogicalType for the same input, leading to issues when the LogicalTypes are compared to ensure they are compatible. For instance, PlannerTypeUtils.isAssignable() returns false for a DataType created from BasicArrayTypeInfo (leading to the ValidationException above).
> The full stacktrace is the following:

> org.apache.flink.table.api.ValidationException: Type LEGACY(BasicArrayTypeInfo<String>) of table field 'my_array' does not match with type BasicArrayTypeInfo<String> of the field 'my_array' of the TableSource return type.
