mapred.fairscheduler.loadmanager - An extension point that lets you specify a class that determines how many maps and reduces can run on a given TaskTracker. This class should implement the LoadManager interface. By default the task caps in the Hadoop config file are used, but this option could be used to make the load based on available memory and CPU utilization for example.
Has someone implemented a loadmanager that does something similar to capacity scheduler's resource base scheduling? Even experimentally?
