I don't understand how these are comparable. Hadoop solved a hard problem that nobody had. Docker solves a simple problem that everyone has. It would make sense if you're talking about kubernetes and using it to build hundreds of microservices because it's currently in fashion. Whether you're using Docker, Packer, Ansible or whatever doesn't matter. They are all a solution to the same problem and saying one is better basically boils down to saying which brand of hammer is better.
