Umesh K commented on HADOOP-12741:
----------------------------------
Thanks actually one third party Java library within my company uses my Java
library. Now that third party library calls this method and does some
processing using my code and then in the end it does checking if any threads
are running then it just does not stop and it throws error that some threads
are running so to avoid this I need to kill this background thread.
> 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.
