Zoltan Farkas commented on AVRO-2072:
-------------------------------------
Applying the patch results in some test failures:
Failed tests:
TestReadingWritingDataInEvolvedSchemas.intUnionIsNotConvertedToFloatUnion
Expected test to throw (an instance of org.apache.avro.AvroTypeException and
exception with message a string containing "Found int, expecting union")
TestReadingWritingDataInEvolvedSchemas.longUnionIsNotConvertedToFloatUnion
Expected test to throw (an instance of org.apache.avro.AvroTypeException and
exception with message a string containing "Found long, expecting union")
TestReadingWritingDataInEvolvedSchemas.longWrittenWithUnionSchemaIsConvertedToFloatDoubleUnionSchema:205
expected: java.lang.Double<42.0> but was: java.lang.Float<42.0>
> ResolvingGrammarGenerator doesn't implement schema resolution correctly for
> unions

> According to
> [specification|https://avro.apache.org/docs/current/spec.html#Schema+Resolution],
> int and long is promotable to float, but when using SchemaValidator, a union
> with a single int or long branch is not readable by an union with a float
> branch.
