Disable the dynamic snitch... via the hidden but still valid [1]
configuration directive "dynamic_snitch" in cassandra.yaml.

"dynamic_snitch: false"

https://issues.apache.org/jira/browse/CASSANDRA-3229

Given the various other bad edge cases with the Dynamic Snitch (sending
requests to the "wrong" DC on reset, etc.) this might be worth considering
in general... especially with the speculative execution stuff in 2.0...

I do note that https://issues.apache.org/jira/browse/CASSANDRA-6465 has a
patch in 2.0.5, yay...
