Daryn Sharp commented on HADOOP-9070:
-------------------------------------
Yes, I believe HADOOP-8999 is where the change (or bulk of it) was made. My
memory is fuzzy, but I think there was an existing case where a malformed
protobuf exception was generated when the client wasn't reading a final
response. The change is largely intended to support PLAIN and/or other future
SASL mechanisms, but it's definitely a bug that the client and server cannot be
sure that SASL has completed.
