Colin Patrick McCabe commented on HADOOP-9975:
----------------------------------------------

will hdfs-fuse have to be updated to use this new relogin method?

> 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.
