According to the configuration, parameters you're using are still valid in
3.7: https://github.com/apache/cassandra/blob/cassandra-3.7/
conf/cassandra.yaml#L184-L194.

If I had to guess, I would say you have an indentation issue. When you
uncommented those properties, did you remove "#" - 1 character - or "# " -
2 characters - including the space? If I remember correctly, YAML is
sensitive to this kind of stuff. I would try that or some other similar
tool in case of doubts:
