--------------------------------------------
[~sumanth.pasupuleti] I reassigned the tiket to [~azotcsit] as he provided a
patch for that ticket. I hope it is fine with you.
[~azotcsit] Thanks a lot for the patch, I might not be able to review it
properly before a couple of week.
I had a quick look at your patch and one thing that would be gret is if you
could had some unit tests to test the behavior of the changes.
> 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
> Components: Feature/Authorization
> Reporter: Sumanth Pasupuleti
> Assignee: Alexey Zotov
> Priority: Normal
> Fix For: 4.x
>
> Time Spent: 20m
> Remaining Estimate: 0h

> 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.
