What about for provisioning clusters that don't require Hadoop. I suppose this could be akin to the comment about Redis -- we're working on deploying Kafka, Storm, and Zookeeper (none of which need Hadoop), and provisioning and node management (membership, leader election) in a dynamic environment (e.g. AWS autoscaling) is not at all obvious. There's also a paucity of substantive information about scaling these clusters dynamically.
