The current craze of Docker has everyone sticking their processes inside a container… but do you really understand cgroups and how they work? Do you understand the difference between CPU Sets and CPU Shares? Spark is a Scala application that lives inside a Java Runtime, do you understand the consequence of what impact the cgroup constraints have on the JRE?
