    Description

      CompositeService.init(Configuration) saves the configuration passed in and passes the same instance down to all managed services. This means a change in the configuration of one child could propagate to all the others.

      Unless this is desired, the configuration should be cloned for each child.

      Fast and easy fix; tests can be added to those coming in MAPREDUCE-4014
