Hi @jaejaes    Looks like you are trying to make a libname connection to kerberized hadoop. Error shows that the ticket you (SAS Session) are trying to use has expired. You will have to generate a new ticket and launch a new SAS Session using the updated ticket to make a successful connection.   Incase you are new to the setup, its better if you reach out to your site administrator to understand how you can generate a new ticket. Thanks! ... View more
