Hi guys, I have a Cassandra 2.1.8 Community cluster running with AllowAllAuthorizer and have to change it, so I can implement permissions in different users. As I've checked in the docs, seems like a simple change, from AllowAllAuthorizer to CassandraAuthorizer in cassandra.yaml. However, I'm a litte concerned about the performance of the cluster while I'm restarting all the nodes. Is it possible to have any downtime (access errors, maybe), as all the data was created with AllowAllAuthorizer? --
