Luke Lu commented on HADOOP-9421:
---------------------------------
bq. Simply protobuf-ing the existing sasl protocol isn't necessarily going to
give us the flexibility we need going forward.
Using protobuf with only one required version field for client request and all
optional fields for server response should cover (for protocol evolution) all
the cases mentioned here and else where (HADOOP-9392 etc.). Do you have any
specific concern about this approach?
The main concern is that it may take a while to address all the related issues
for SASL, given the all parallel evolving JIRAs in this area. Resolving this
JIRA first would allow a scale testing of RPC v9 for 2.0.5 beta ASAP to
discover any potential issues early.
