Doug Cutting commented on HADOOP-7557:
--------------------------------------

> Currently it does support multiple payload types

Are you referring to Avro?  If so, that's not quite right.  Avro requests and responses are wrapped in a Writable.  The wire format of all requests and responses is currently Writable.  AvroRpcEngine layers on top of the WritableRpcEngine, embedding Avro in the Writable RPC format on the wire.
