Overview
The MiddleManager node is a worker node that executes submitted tasks. Middle Managers forward tasks to Peons that run in separate JVMs. The reason we have separate JVMs for tasks is for resource and log isolation. Each Peon is capable of running only one task at a time, however, a MiddleManager may have multiple Peons.
