Cassandra 1.2.19 We would like to turn on Cassandra's internal security (PasswordAuthenticator and CassandraAuthorizer) on the ring (away from AllowAll). (Clients are already passing credentials in their connections.) However, I know all nodes have to be switched to those before the basic security objects (system_auth) are created. So, an outage would be required to change all the nodes, let system_auth get created, alter system_auth for replication strategy, create all the users/permissions, repair system_auth.
For DataStax, there is a TransitionalAuthorizer that allows the system_auth to get created, but doesn't really require passwords. So, with a double, rolling bounce, you can implement security with no downtime. Anything like that for open source? Any other ways you have activated security without downtime? Sean R.
