Description

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.
