Brandon Williams commented on CASSANDRA-18559:
----------------------------------------------
bq. Without rack/dc information from the snitch, should unencrypted rack or dc
connections be permitted?
GPFS learns this information from gossip though which needs a connection so I
think we have a chicken/egg problem.
bq. As a workaround, can the snitch be made to supply rack/dc for all the
members of the cluster?
You would have to change snitches (ignoring PFS compat mode) and doing this
kind of breaks what GPFS is designed to do, which is save operators from
specifying all of this info and replicating it on every node themselves.
