Sanjay Radia commented on HADOOP-9820:
--------------------------------------
You have optimized as per item 6 on your comment. Hence the javadoc for
getInputStream and getOutputStream are incorrect. It should say something like
"Get SASL wrapped xxxputStreeam if it is sasl wrapped otherwise return original
stream".
> RPCv9 wire protocol is insufficient to support multiplexing

> RPCv9 is intended to allow future support of multiplexing. This requires all
> wire messages to be tagged with a RPC header so a demux can decode and route
> the messages accordingly.
> RPC ping packets and SASL QOP wrapped data is known to not be tagged with a
> header.
