Sorry about the confusing omission of the upgrade instructions from NEWS.txt, the oversight there was mine in the course of CASSANDRA-7653. Dropping those tables is absolutely what you need to do in order to trigger C* to switch over to using the new role-based tables following an upgrade to 2.2+

Some update. I went through this blog: https://www.instaclustr.com/5-things-you-need-to-know-about-cassandra-2-2/ and deleted these three tables (with fingers crossed): system_auth.credentials system_auth.users system_auth.permissions Now I seem to be able to use RBAC to modify permissions.
