When I first brought this cluster online, the storage-conf.xml file had a few cache capacities set. Since then, we've completely changed how we use cassandra's caching, and no longer use any of the caches I setup in the original configuration.
I'm finding that cassandra doesn't want to keep my new cache settings. I can disable those caches with setcachecapacity, check cfstats and see that they are disabled, but within a few minutes, cfstats is reporting that the caches are back. Anything I can do?
