      Description

      Currently hadoop loads its classes and caches them in the Configuration class. Even if the user swaps a class's jar at runtime, hadoop will continue to use the cached classes when using reflection to instantiate objects. This limits the usefulness of things like HADOOP-10285, because the admin would need to restart each time they wanted to change their queue class.

      This patch is to add a way to refresh the class cache, by creating a new refresh handler to do so (using HADOOP-10376)
