> We have some non-secure clusters taking live traffic in production from active clients. We want to enable client to node encryption on these clusters. Once we set the client_encryption_options enabled to true in yaml and bounce a cassandra node in the ring, the existing clients that do not do SSL will fail to connect to that node.
> There does not seem to be a good way to roll this change with out taking an outage. Can we implement a transitional mode in C* that will accept both encrypted and non-encrypted client traffic? We would enable this during transition and turn it off after both server and client start talking SSL.
