Subject resource based scheduling - fairscheduler
Date Wed, 18 Apr 2012 04:32:54 GMT
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?
