Fixed issues in Zeppelin

This section lists the issues that have been fixed since the previous version.

CDPD-1683: Zeppelin demo users have been removed
Use cluster users to access Zeppelin. For information on provisioning users in CDP, see Onboarding users.

Workaround: Use an available interpreter. For Spark functionality, use the Livy interpreter.

Workaround: None.
