> {{GossipingPropertyFileSnitch}} (GPFS) has a compatibility mode which fallbacks to {{PropertyFileSnitch}}
(PFS) to fetch rack/dc info from {{conf/cassandra-rackdc.properties}} when a node info is
not found in Gossip.
> The problem is that we supply a default {{conf/cassandra-rackdc.properties}}, which is
loaded in clusters (as shown in the log below) and may affect ring layout before gossip settles
potentially leading to issues such CASSANDRA-13948.
> {code:none}
> INFO  [main] 2017-10-12 14:39:32,928 GossipingPropertyFileSnitch.java:64 - Loaded cassandra-topology.properties
for compatibility
> {code}
> I see 2 options to preven this from causing similar problems in the future:
> a) Remove PFS compatibility mode
> a) Move {{conf/cassandra-rackdc.properties}} to {{examples}} or {{conf/examples}}.
