----------------------------------
Summary: ReflectData#isNonStringMap returns true for
org.apache.avro.util.Utf8 keys
Key: AVRO-2058
URL: https://issues.apache.org/jira/browse/AVRO-2058
Project: Avro
Issue Type: Bug
Components: java
Affects Versions: 1.8.2
Reporter: Sam Schlegel
Priority: Critical
Since {{org.apache.avro.util.Utf8}} does not have an
{{org.apache.reflect.Stringable}} notation, and is not in
{{org.apache.avro.specific.SpecificData#stringableClasses}},
{{ReflectData#isNonStringMap}} returns true. This also causes
{{ReflectData#isArray}} to return true for maps with Utf8 keys, and thus
{{GenericData#resolveUnion}} fails as well. This ultimately causes
{{ReflectData#write}} to fail for schemas that contain a union that contains a
map, where the data uses Utf8 for strings.
