Doug Cutting updated AVRO-864:
------------------------------
Attachment: AVRO-864.diff
Here's a slightly different version of the patch. Instead of catching
exceptions it calls super directly for generic and specific records. The
provided unit test still passes.
> NoSuchFieldException when emitting record with array of union of records in
> mapred

> I tried to convert data records currently in a custom format into avro
> records via a map-only job. To allow for optional record fields I followed
> the workaround sketched by Doug in AVRO-519 using the generic API.
> When emitting the resulting records a "NoSuchFieldException" is thrown when
> trying to resolve the union types: Only the methods declared in ReflectData
> seem to be called, the implementation in GenericData is skipped.
