Cassandra is a distributed database meant to run across multiple systems. Is your existing Java application distributed as well? Does "maintain control" mean "exclude end users from connecting to it and making changes" or merely "provisioning and keep it running well operationally for the application"? Honestly, either of those seem like a lot to ask right now for any solution requiring the scalability that Cassandra provides.
That said, I've done embeded PostgreSQL in the past. Not distributed mind you. And it was on an appliance. We picked PG because it's super reliable and very good at recovering from all kinds of evil things that customers do... pulling power cords, etc. I don't think any of our customers even knew we were using PG unless they looked in the Licensing section of the manual. Personally, I don't think Cassandra is there yet where it can be a opaque datastore from the end user perspective- especially if you're distributing it as part of a software application and don't have full control over the hardware/environment. Not to say Cassandra hasn't been reliable for us, but it's far from "install it and forget it". Simple things like dealing with network/node outages or adding/removing new nodes are complicated enough that I'd hesitant to automate without some human familiar with Cassandra being involved.
