Sean Busbey commented on AVRO-997: ---------------------------------- AFAIK, this patch does require isEnum everywhere; that's why it was originally pushed out to 1.8.0. It even adds tests to make sure using a String or Java enum fails. Can you be more specific about where there's a gap? > Union of enum and null cannot be serialized > ------------------------------------------- > > Key: AVRO-997 > URL: https://issues.apache.org/jira/browse/AVRO-997 > Project: Avro > Issue Type: Bug > Affects Versions: 1.5.1 > Reporter: Aaron Kimball > Assignee: Sean Busbey > Fix For: 1.8.0 > > Attachments: AVRO-997.patch, AVRO-997.patch, AVRO-997.patch, > AVRO-997.permissive-generic-api.patch > > > I have a schema like: > {code} > [ > { > "type": "enum", > "name": "Gender", > "symbols": ["M", "F"] > }, > { > "type" : "record", > "name" : "Foo", > "fields" : [ > { "type" : ["Gender", "null"], "name" : "gender" }, > ... > ] > } > ] > {code} > I build a record like {{Foo foo = new Foo(); foo.gender = Gender.M;}} > When I go to serialize this, I get: > {code}Not in union > [{"type":"enum","name":"Gender","symbols":["M","F"]},"null"]: M > at > org.apache.avro.generic.GenericData.resolveUnion(GenericData.java:482) > at > org.apache.avro.generic.GenericDatumWriter.write(GenericDatumWriter.java:70) > at > org.apache.avro.generic.GenericDatumWriter.writeRecord(GenericDatumWriter.java:104) > at > org.apache.avro.generic.GenericDatumWriter.write(GenericDatumWriter.java:65) > at > org.apache.avro.generic.GenericDatumWriter.write(GenericDatumWriter.java:57) > {code} -- This message was sent by Atlassian JIRA (v6.3.4#6332)
