Subject [jira] [Updated] (CASSANDRA-9590) Support for both encrypted and unencrypted native transport connections
Date Fri, 28 Aug 2015 15:21:45 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-9590?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Stefan Podkowinski updated CASSANDRA-9590:
------------------------------------------
    Description: 
Enabling encryption for native transport currently turns SSL exclusively on or off for the
opened socket. Migrating from plain to encrypted requires to migrate all native clients as
well and redeploy all of them at the same time after starting the SSL enabled Cassandra nodes.


This patch would allow to start Cassandra with both an unencrypted and ssl enabled native
port. Clients can connect to either, based whether they support ssl or not.

This has been implemented by introducing a new {{native_transport_port_ssl}} config option.

There would be three scenarios:
* client encryption disabled, {{native_transport_port}} unencrypted, {{native_transport_port_ssl}}
not used
* client encryption enabled, {{native_transport_port_ssl}} not set, {{native_transport_port}}
encrypted
* client encryption enabled, {{native_transport_port_ssl}} set, {{native_transport_port}}
unencrypted, {{native_transport_port_ssl}} encrypted

This approach would keep configuration behavior fully backwards compatible.
