Work Description: davidov541 commented on issue #933: HIVE-21218: Adding
support for Confluent Kafka Avro message format
URL: https://github.com/apache/hive/pull/933#issuecomment-596135777
OK, I've verified that SimpleRecord is no longer in the generated JAR, and
that tests run appropriately. I'm currently building a distribution to test in
my system again, at which point I'll be confident this PR is correct and ready.

> 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.
