> Avro SerDe doesn't handle serializing Nullable types that require access to a
> Schema
> ------------------------------------------------------------------------------------
>
> Key: HIVE-3528
> URL: https://issues.apache.org/jira/browse/HIVE-3528
> Project: Hive
> Issue Type: Bug
> Components: Serializers/Deserializers
> Reporter: Sean Busbey
> Labels: avro

>
> 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.
