For Apache Storm, use Kestrel

There is a lot in this thread that is interesting. This is coming from Nathan Marz, the guy who invented Storm. He says he uses Kestrel, so that is a big endorsement.

You want to make sure that your spout source can support the out of order acking that Storm requires for guaranteed message processing. We use Kestrel because it has this property and is the simplest. RabbitMQ is another good one to consider.
