> The RPC client currently constructs the kerberos principal based on the a config value, usually with an _HOST substitution.  This means the service principal must match the hostname the client is using to connect.  This causes problems:
> * Prevents using HA with IP failover when the servers have distinct principals from the failover hostname
> * Prevents clients from being able to access a service bound to multiple interfaces.  Only the interface that matches the server's principal may be used.
> The client should be able to use the SASL advertised principal (HADOOP-9698), with appropriate safeguards, to acquire the correct service ticket.
