Where are you running the pig script from - your local machine or one of the nodes in the cluster or ? I would think it wouldn't matter which address you use, but what interface it's using. So if the internal and public address are both using the same interface, then you should be able to connect to cassandra from your local machine using the public address. That's what I do with EC2. I use the internal address to connect when I'm connecting within the region and the public address when I'm connecting from my local machine.
I've never done a different address for rpc_address and listen_address for that configuration, so there might be peculiarities there that I wouldn't have seen.
