I couldn't find any similar issue as this one so I'm creating one.
I noticed that doing nodetool describecluster shows a different Snitch Information as to what is being set in the configuration file.
My setup is hosted in AWS and I am using Ec2Snitch.
cassandra@cassandra3$ nodetool describecluster
I checked via MX4J and it shows the same, I haven't verified tho using a different Snitch and I am using 2.2.6 above and 3.0.X
