A customer reported the issue when GPFS was used. The cluster was on AWS
multi-region. It could be reproduced in house on DSE 4.8.6 (C* 2.1.13).

> Ec2MultiRegionSnitch causing internode encryption to always connect on secure
> port, even when set to 'dc'

> Key: CASSANDRA-9386
> URL: https://issues.apache.org/jira/browse/CASSANDRA-9386
> Project: Cassandra
> Issue Type: Bug
> Reporter: Blake Eggleston
> Priority: Minor
> Fix For: 2.1.x

>
> [~csplinter] found a problem the Ec2MultiRegionSnitch is causing with dc
> internode encryption with 2.0.x:
> {quote}
> When nodes in the same DC are started on _(DSE)_ 4.6.x _(C* 2.0.x)_ they use
> private IPs but start communicating over the ssl_storage_port (7001) instead
> of the normal storage_port (7000), despite having internode_encryption set to
> "dc".
> {quote}
> It looks like the issue was introduced with CASSANDRA-5542. The OTCPool in
> 2.0.x is now using the ip address it's attempting to connect to (in our case,
> the private ip) to determine if the remote node is in the same dc. Since all
> of the gossiped state (including dc) is associated with the node's public ip,
> it can't find any info for it, and connects to it over the ssl port.
> I need to do some more investigation, but I think having the
> ReconnectableSnitchHelper maintain a map of private->public ips and
> consulting that before determining dc/rack info would fix the issue.
