[jira] [Created] (CASSANDRA-15523) Update default snitch from SimpleSnitch to GossipingPropertyFileSnitch

Jeremy Hanna created CASSANDRA-15523:
----------------------------------------

             Summary: Update default snitch from SimpleSnitch to GossipingPropertyFileSnitch
                 Key: CASSANDRA-15523
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-15523
             Project: Cassandra
          Issue Type: Improvement
          Components: Local/Config
            Reporter: Jeremy Hanna


Traditionally the project has had {{SimpleSnitch}} as the default primarily because it makes it easy for a user to download the software and start Cassandra without changing any defaults and it will just work.  However, {{SimpleSnitch}} is not datacenter aware.  {{GossipingPropertyFileSnitch}} could also be used as the default and would make the default snitch be datacenter aware.  The user simply needs to update the local datacenter and rack names on each node and when it joins the cluster, it will propagate that topology information around the ring.

This ticket would be to update the default from {{SimpleSnitch}} to {{GossipingPropertyFileSnitch}} to make the onboarding experience better for those who don't know to change this default if they intend to expand to multiple datacenters without too much hassle.
