Subject [jira] [Created] (CASSANDRA-5290) Refactor SSL support to make it possible enable without total cluster downtime
Date Tue, 26 Feb 2013 10:04:13 GMT
Marcus Eriksson created CASSANDRA-5290:
------------------------------------------

             Summary: Refactor SSL support to make it possible enable without total cluster
downtime
                 Key: CASSANDRA-5290
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-5290
             Project: Cassandra
          Issue Type: Improvement
            Reporter: Marcus Eriksson
            Priority: Minor


should be possible by doing something similar to what compression does today:

* node A connects to node B, indicating that it wants SSL
* node A and B upgrade/wrap sockets
* node B must still be able to talk to A (and all other nodes) without SSL

nothing secret is shared during hand shake phase

one difference compared to compression is that after the cluster is rolled there must be a
way to not allow any non-ssl talk at all to avoid any plaintext-communication due to configuration
mistakes. this should be doable via configuration and perhaps JMX
