[jira] [Commented] (HADOOP-9957)
UserGroupInformation.checkTGTAndReloginFromKeytab() do the same thing as
method reloginFromKeytab()

Kai Zheng commented on HADOOP-9957:
-----------------------------------
Checking TGT looks like to be intended, did you check that? Are you working on a bug or just want to cleanup this? If the later, HADOOP-9797 probably did that.
> UserGroupInformation.checkTGTAndReloginFromKeytab() do the same thing as method reloginFromKeytab()

> 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.
