Vinayakumar B commented on HADOOP-12741:
----------------------------------------
Can you point, where exactly UGI#loginUserFromKeytab() is creating background
thread?
>From the code I am seeing, creation of daemon thread is done only when
>{{UGI#loginUserFromSubject(..)}} is called.
> UserGroupInformation.loginUserFromKeytab() creates background thread which is
> not getting killed even after application exited

> Hi UserGroupInformation.loginUserFromKeytab() method creates one background
> thread for keytab refresh after every 10 hours I guess. One of my application
> is using UserGroupInformation.loginUserFromKeytab() but at the end of my
> application the background thread created by it does not get killed it keeps
> on running. How do I kill/stop thead started by
> UserGroupInformation.loginUserFromKeytab()? Please guide or please provide
> method inside UserGroupInformation so that we can kill it or stop it. Thanks
> in advance.
