---------------------------------
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.
