> It would be nice if the MR ApplicationMaster had the notion of admin options in addition to the existing user options much like we have for map and reduce tasks, e.g.: mapreduce.admin.map.child.java.opts vs. mapreduce.map.java.opts.  This allows site-wide configuration options for MR AMs but still allows a user to easily override the heap size of the AM without worrying about dropping other admin-specified options.
