--------------------------------------
Summary: Coercion problem with ConvertAvroSchema processor
Key: NIFI-7881
URL: https://issues.apache.org/jira/browse/NIFI-7881
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Affects Versions: 1.12.1
Reporter: Dominik Przybysz
I have two schemas - input one has Map<String, UNION<null, String, Double>>
field and output schema has the same field with type Map<String, UNION<null,
String>>.
In such example Double should be coerced to String, but it is still Double and
processor fails to write avro object because of incompatible field type.
I created two similar tests:
- for AvroRecordConverter (used by ConvertAvroSchema) which fails
- for AvroTypeUtil (used in some other components which write avro objects) and
here the test passes
The tests are here:
