Sanjay Radia commented on HADOOP-9421:
--------------------------------------
bq. I'm only suggest that we simply send a length + RpcSaslProto after the
connection header (analogous to the current authmethod byte but more
extensible), which open up many opportunities to reduce auth round-trips in the
future without future client baggage.
To echo this. This jira started out as adding just the length to the reply,
then Protobuf and now a lot more. We can only afford a simple change for hadoop
2.x GA. Anything more adds too many changes to go into 2.x since it will
require extensive testing including performance testing.
> Convert SASL to use ProtoBuf and add lengths for non-blocking processing
