By the way, just noticed a typo in my email below. I'm using the correct keyspace name in all locations on the cluster... however in my examples below, I used MyKeyspace in some spots and MDR in other spots, but in the cluster I'm specifying the same keyspace name everywhere, so that's not the issue.
