> Currently, RPC client caches the conf that was passed in to its constructor 
> and uses that same conf (or values obtained from it) for every connection it 
> sets up. This is not sufficient for security since each connection needs to 
> figure out server's Kerberos principal on a per-connection basis. It's not 
> reasonable to expect the first conf used by a user to contain all the 
> Kerberos principals that her future connections will ever need. Or worse, if 
> her first conf contains an incorrect principal name, it will prevent the user 
> from connecting to the server even if she later on passes in a correct conf 
> on retry (by calling RPC.getProxy()).
