      It does not appear that functions defined in system.js are available to map reduce jobs in 2.4.0-rc0. In 2.2.0 and before these functions were available. Without the ability to add functions to system.js for map reduce jobs, jobs with common functionality or that rely on JS libraries become unmanageable. Also, the full jobs must be sent to the server rather than simply calling a function defined in system.js
