Apache Mesos is a distributed system that is kind of a "bottom layer" for computations and storage (whether in-memory or on disk).
Apache Spark is a distributed application that runs on top of Mesos and does computations that takes advantage of cluster computing. It can do classic MapReduce or other algorithms that you write using its API.
Kubernetes is a distributed system that runs Docker in a cluster. Docker is a way to run sandboxed applications. Kubernetes can run on Mesos.
