Yes, and if they worked anywhere near as good as what Cloudera has implemented, I would have recommended them. But thus far the performance hit is noticeable and the CLI management of them is cumbersome at best. Now I will admit that I have only been playing with the ACLs over the past three days, but if you have had different results I would love to hear about them.
