---------------------------------

             Summary: Adding relogin() method to UGI
                 Key: HADOOP-9975
                 URL: https://issues.apache.org/jira/browse/HADOOP-9975
             Project: Hadoop Common
          Issue Type: Improvement
            Reporter: Kai Zheng
            Assignee: Kai Zheng


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.
