I assume some users are connecting to Spark in Zeppelin through Livy. It seems Livy doesn't support `hadoop.security.auth_to_local` - filed https://issues.apache.org/jira/browse/LIVY-481
Has anyone ran into this issue? It seems Livy's `livy.server.auth.kerberos.name-rules` config was trying to workaround this (just guessing based on the config name), but I can't find any documentation on this either. Thanks! Ruslan
