erictcgs commented on issue #22911: [SPARK-25815][k8s] Support kerberos in client mode, keytab-based token renewal. URL: https://github.com/apache/spark/pull/22911#issuecomment-447349112 Had a chance to try it - the driver pod is now getting the keytab mounted and is able to generate delegation token, so that's looking good. I'm still having an issue where the executors seem to not be using the dt and so are getting denied access - are they also supposed to have hadoop_conf_dir set?
