Doing a simple 'find' in the source checkout for name pattern
'Scheduler' should reveal pretty relevant hits. We do name our Java
classes seriously :)

You can override the mapred-site.xml placed property
'mapred.jobtracker.taskScheduler' to specify a custom scheduler (or a
supplied one, such as Fair
[http://hadoop.apache.org/docs/r1.1.2/fair_scheduler.html] or Capacity
Remove the configuration override, and it will always go back to the
default FIFO based scheduler, the same whose source has been linked
Are you unsure about this?
