Review comment:
Agreed, but this seems tangential to the issue at hand. It could be
committed without additional tests on the schema.

> Key: HIVE-21218
> URL: https://issues.apache.org/jira/browse/HIVE-21218
> Project: Hive
> Issue Type: Bug
> Components: kafka integration, Serializers/Deserializers
> Affects Versions: 3.1.1
> Reporter: Milan Baran
> Assignee: Milan Baran
> Priority: Major
> Labels: pull-request-available
> Attachments: HIVE-21218.2.patch, HIVE-21218.patch

> Time Spent: 4h 20m
> Remaining Estimate: 0h

> According to [Google
> groups|https://groups.google.com/forum/#!topic/confluent-platform/JYhlXN0u9_A]
> the Confluent avro serialzier uses propertiary format for kafka value -
> <magic_byte 0x00><4 bytes of schema ID><regular avro bytes for object that
> conforms to schema>.
> This format does not cause any problem for Confluent kafka deserializer which
> respect the format however for hive kafka handler its bit a problem to
> correctly deserialize kafka value, because Hive uses custom deserializer from
> bytes to objects and ignores kafka consumer ser/deser classes provided via
> table property.
> It would be nice to support Confluent format with magic byte.
> Also it would be great to support Schema registry as well.
