Will Gorman updated AVRO-1512:
------------------------------
Attachment: test.thrift
Attaching the Thrift IDL used to reproduce the issue. It was compiled with
Thrift 0.7.0, matching the version of libthrift currently used by avro-thrift.
> Error serializing TUnion with avro-thrift

> Key: AVRO-1512

> Components: java

>
> Attempting to serialize a Thrift union type (TUnion) with avro-thrift
> produces an error like the following:
> {noformat}
> org.apache.avro.AvroRuntimeException: Unknown datum type
> org.apache.avro.thrift.test.FooOrBar: <FooOrBar foo:foo>
> at
> org.apache.avro.generic.GenericData.getSchemaName(GenericData.java:639)

> at org.apache.avro.thrift.TestThrift.check(TestThrift.java:83)
> at org.apache.avro.thrift.TestThrift.testStruct(TestThrift.java:60)
> {noformat}
> Upon investigation it appears that ThriftData#isRecord intentionally does not
> accept TUnion types as Avro records and so GenericData is unable to determine
> an Avro type for the datum. However, ThriftData#getSchema does generate an
> Avro record schema for Thrift union types.
