Well, they were supposed to be.
Masters and clients are java version "1.7.0_65", data nodes are java version "1.7.0_79".
Guess I'll be upgrading the masters and clients in the morning.
Thanks Mark. You are seriously all over this group. I hope you're getting paid for all your free help! If not, I'll have to send you a beer or 12. I know you've personally answered many of my questions!
