[jira] [Created] (CASSANDRA-15936) Extend IInternodeAuthenticator to inspect existing connections

Yifan Cai created CASSANDRA-15936:
-------------------------------------

             Summary: Extend IInternodeAuthenticator to inspect existing connections
                 Key: CASSANDRA-15936
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-15936
             Project: Cassandra
          Issue Type: Improvement
          Components: Messaging/Internode
            Reporter: Yifan Cai
            Assignee: Yifan Cai


The internode authenticator ({{IInternodeAuthenticator}}) should support inspecting the existing connections and close the connections if no longer permitted. 

It would be useful and necessary for the dynamic internode authenticator implementations, which may stop authenticating connections between some nodes at a later time point. 

The current interface only authenticates on a connection during tcp/nodes handshake. It leaves the existing connection alive and the nodes are still able to communicate, after the authenticator has been updated to not permit connections between the nodes.
