Jeremy Hanna commented on CASSANDRA-6124:
-----------------------------------------

To add to the discussion on the ticket, [~patricioe] said on the dev list "LOCAL_ONE is definitely
a work around. We are currently running with my patch in production to avoid establishing
connections to others DC which is the intention of the patch."

> - 3 cassandra nodes (offline DC)

offline dc)
