Daryn Sharp commented on HADOOP-9421:
-------------------------------------
bq. It's an "insane" solution for HA because HA will not be seamless due the
race condition I mentioned. It's fixable with more negotiate rounds with more
logic though
There no race. Let's say the client gets a negotiate with that server's
principal user & host, but the connection is lost before/during the SASL
exchange. When the client reconnects it will get a new negotiate for that
server containing that server's principal user and host. The authentication to
the failover server will be seamless. :)
> Convert SASL to use ProtoBuf and provide negotiation capabilities
