Sean Busbey commented on HIVE-3528:
-----------------------------------
In that case, since 0.11 hasn't gone out yet, either including error
information here or starting another JIRA is fine.
I'd recommend including the error information here until we can determine if
your problem is the one that this patch is supposed to fix.
> Avro SerDe doesn't handle serializing Nullable types that require access to a
> Schema

> Deserialization properly handles hiding Nullable Avro types, including
> complex types like record, map, array, etc. However, when Serialization
> attempts to write out these types it erroneously makes use of the UNION
> schema that contains NULL and the other type.
> This results in Schema mis-match errors for Record, Array, Enum, Fixed, and
> Bytes.
> Here's a [review board of unit tests that express the
> problem|https://reviews.apache.org/r/7431/], as well as one that supports the
> case that it's only when the schema is needed.
