Determines the location of nodes by rack and data center.
This snitch uses a user-defined description of the network details located in the cassandra-topology.properties file. Use this snitch when your node IPs are not uniform or if you have complex replication grouping requirements. When using this snitch, you can define your data center names to be whatever you want. Make sure that the data center names you define correlate to the name of your data centers in your keyspace options. Every node in the cluster should be described in the cassandra-topology.properties file, and this file should be exactly the same on every node in the cluster.
