Below are suspected locations of interest regarding the CDH3 (0.20.2) task scheduler:
src/mapred/org/apache/hadoop/mapred/TaskScheduler.java - Topmost interface for all schedulers.
src/mapred/org/apache/hadoop/mapred/JobQueueTaskScheduler.java - Default FIFO Scheduler.
src/contrib/fairscheduler - Fair Scheduler.
src/contrib/capacity-scheduler - Another Scheduler.
