> In current Hadoop UGI implementation, it has API methods like
> reloginFromKeytab() and reloginFromTicketCache(). However, such methods are
> too Kerberos specific and also involves login implementation details, it
> would be better to add generic relogin() method regardless authentication
> mechanism. This is possible since relevant authentication specific parameters
> like principal and keytab are already passed and saved in the UGI object
> after initial login.
