Scott Chen commented on MAPREDUCE-961:
--------------------------------------

I see. Your pseudo code is very clear. Thanks.
I think this definitely makes more sense than first looking at all the map 
tasks and then looking at all the reduce tasks.


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

> 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.
