-----------------------------------
Summary: UserGroupInformation.checkTGTAndReloginFromKeytab() do
the same thing as method reloginFromKeytab()
Key: HADOOP-9957
URL: https://issues.apache.org/jira/browse/HADOOP-9957
Project: Hadoop Common
Issue Type: Wish
Components: security
Reporter: Aimee Cheng
The methods checkTGTAndReloginFromKeytab() and reloginFromKeytab() in
UserGroupInformation actually are do the same things. Now reloginFromKeytab()
will check the TGT expire time, if fresh, then will not relogin, just as what
checkTGTAndReloginFromKeytab() does. I suggest maybe we can still let
reloginFromKeytab() not check the TGT and provide a way to let develop can
control when to relogin. While maybe we can just remove the
checkTGTAndReloginFromKeytab() method.
