CompositeService should clone the Configurations it passes to children
----------------------------------------------------------------------
Key: MAPREDUCE-4016
URL: https://issues.apache.org/jira/browse/MAPREDUCE-4016
Project: Hadoop Map/Reduce
Issue Type: Sub-task
Components: mrv2
Affects Versions: 0.23.1, 0.24.0
Reporter: Steve Loughran
{{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
