KafkaSerDe doesn't support topics created via Confluent Avro serializer

    Details

    • Target Version/s:
    • Release Note:
      KafkaSerDe now supports Confluent Avro message format.

      Description

      According to Google groups 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.
