> 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.
