Feng Peng commented on HIVE-3163:
---------------------------------
Cool. I guess our use case is kind of different from yours. We already have a
ProtobufDeserializer in Elephantbird, which is currently using the
ReflectionObjectInspector and thus getting a different set of fields from the
original protobuf def. Since Elephantbird already extracts the field names from
the protobuf objects, for the time being we will just write an OI on top of it,
and replace it when the Hive ProtbobufDeserializer is finalized.
Thanks,
Feng

> There are some serdes: ThriftDeserializer and AvroDeserilizer which
> contain the column information. I mean, the user does not need to specify the
> column schema.
> Currently, this information is hard-coded. SerDeUtils has a method to get this
> information from the name of the serde.
> Ideally, Deserializer should be extended to add this method.
