Daryn Sharp commented on HADOOP-9421:
-------------------------------------

I've got a patch working.  BUT... A pre-existing problem is that after the 
connection header is sent, the client expects to be in sasl mode.  When it gets 
an RPC error, such as invalid rpc version or unsupported serialization, it 
blows up trying to decode it as SASL.  I think I am going to have to wrap the 
SASL exchange with {{RpcRequestHeaderProto}} so the client can determine if the 
response is a RPC or SASL protobuf.
                
> Convert SASL to use ProtoBuf and add lengths for non-blocking processing
