------------------------------------------

             Summary: config option to allow GossipingPropertyFileSnitch to use the "reconnect trick"
                 Key: CASSANDRA-5630
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-5630
             Project: Cassandra
          Issue Type: Improvement
          Components: Core
    Affects Versions: 1.2.5
            Reporter: Chris Burroughs
             Fix For: 1.2.6


Currently we have two instances of the "use the local ip inside the same datacenter trick":
 * Ec2MultiRegionSnitch -- which is obviously EC2 specific
 * YamlFileNetworkTopologySnitch -- which is powerful but verbose

There is no reason that GossipingPropertyFileSnitch could not (optionally) do the same.  Attached is a patch that adds a preferLocal (default==false==current-behavior) property to GossipingPropertyFileSnitch and does the IEndpointStateChangeSubscriber reconnect dance.  I based it on the other snitches but admit that they still seem fairly magical to me.  This could be a new class that extends GossipingPropertyFileSnitch, but I could not think of a name that wasn't absurdly long.
