AccessControlException when starting session in a Kerberized cluster

I am using a Kerberized cluster for CDSW. When launching spark2-shell from a terminal, the shell launches fine. However, when I launch a workbench session in CDSW (using Scala engine kernel), I get the following exception. I have already selected to use Kerberos in ths CDSW settings for "Hadoop Authentication". Please let me know what  I am missing. Thanks.
