Daryn Sharp commented on HADOOP-9421:
-------------------------------------
bq. The main thing I'd like to have is be able to evolve client initiation (to
save a round-trip with cached mechs) without having to change the RPC version
again.
Yes, and I haven't forgotten about that but planned to address in the future.
As-is, it would be possible for the client to blindly send the connection
header & INITIATE and just ignore the NEGOTIATE response. I need to consider
how to properly handle IP failover when the cached info is stale.
