> Design and develop a ResouceAwareLoadManager for the FairShare scheduler that dynamically decides how many maps/reduces to run on a particular machine based on the CPU/Memory/diskIO/network usage in that machine.  The amount of resources currently used on each task tracker is being fed into the ResourceAwareLoadManager in real-time via an entity that is external to Hadoop.
