Without ZEPPELIN_IMPERSONATE_CMD and ZEPPELIN_IMPERSONATE_SPARK_PROXY_USER set it should work just fine. However, if you want to setup password-less login, you can use this doc, its was written for Zeppelin-0.6.0 but it works fine https://community.hortonworks.com/content/kbentry/81069/how-to-enable-user-impersonation-for-sh-interprete.html . Also, can you quickly check if you are able to connect to spark with user impersonation?
