> PHOENIX-3189 fixed some logic in construction of a {{ConnectionInfo}} to, 
> when requested by the user, perform the Kerberos login and then construct and 
> cache the ConnectionInfo->ConnectionQueryServices pair.
> This approach only works when the principal that the user provides in the 
> JDBC url is exactly what UGI returns as the short name. Logically equivalent 
> principals will result in re-logging in each time and leaking 
> ConnectionQueryService instances (and thus HConnection and ZooKeeper objects).
> For example, with Kerberos principals there is a default realm which is 
> implied by krb5.conf when not explicitly provided. Thus: {{elserj}} and 
> {{elserj@APACHE}} would be considered logically equivalent (when the default 
> realm is "APACHE"). We should expand the {{isSameName}} check in 
> ConnectionInfo to be a bit smarter.
