Re: property mapred.tasktracker.map.tasks.maximum
Anil is correct:

mapred.tasktracker.{map,reduce}.tasks.maximum == TaskTracker Service
Property. Applies via mapred-site.xml at each TT.

mapred.child.java.opts == Per-Job Overridable Property. Applies via
mapred-site.xml at each client, or via code (JobConf, Job, etc.).
