can we add a KryoRegistrar that will handle adding the default serializer for any subclass of SpecificRecordBase? See the one we have for thrift or protobuf, for instance

actually, we didn't (for some reason) make KryoRegistars for those two cases.

Can you make a function that returns a registrar for a given T? You use something like this in your test.

def SpecificRecordSerializer[T <: SpecificRecordBase : Manifest]: KSerializer[T] = {
implicit val inj = SpecificAvroCodecs[T]
InjectiveSerializer.asKryo
}

def SpecificRecordBinarySerializer[T <: SpecificRecordBase : Manifest]: KSerializer[T] = {
implicit val inj = SpecificAvroCodecs.toBinary[T]
InjectiveSerializer.asKryo
}

def SpecificRecordJsonSerializer[T <: SpecificRecordBase : Manifest](schema: Schema): KSerializer[T] = {
import com.twitter.bijection.StringCodec.utf8
implicit val inj = SpecificAvroCodecs.toJson[T](schema)
implicit val avroToArray = Injection.connect[T, String, Array[Byte]]
InjectiveSerializer.asKryo
}
