ResourceAwareLoadManager to dynamically decide new tasks based on current CPU/memory load on TaskTracker(s)
-----------------------------------------------------------------------------------------------------------

                 Key: MAPREDUCE-961
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-961
             Project: Hadoop Map/Reduce
          Issue Type: New Feature
          Components: contrib/fair-share
            Reporter: dhruba borthakur
            Assignee: dhruba borthakur


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.
