             Summary: Provide a nodetool way of invalidating auth caches
                 Key: CASSANDRA-16404
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-16404
             Project: Cassandra
          Issue Type: Improvement
            Reporter: Sumanth Pasupuleti
            Assignee: Sumanth Pasupuleti


We currently have nodetool commands to invalidate certain caches like KeyCache, RowCache and CounterCache. 
Being able to invalidate auth caches as well can come in handy in situations where, critical backend auth changes may need to be in effect right away for all the connections, especially in configurations where cache validity is chosen to be for a longer duration. An example can be that an authenticated user "User1" is no longer authorized to access a table resource "table1" and it is vital that this change is reflected right away, without having to wait for cache expiry/refresh to trigger.
