on a kerberized cluster i am getting the following error using livy interpreter doing simple sc.version. I ran same sc.version using %spark interpreter with no issues
Error running rest call; nested exception is org.springframework.web.client.HttpClientErrorException: 403 Forbidden
My livy interpreter setting

I have viewed other post on HCC with similar issue. The settings i have displayed above seem to be ok unless someone sees an issue with it.
