> 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.
