I am trying to understand how my cluster is configured to use RAM, like service usage (CLDB, Job Tracker, Task Tracker etc)
warden.conf has all properties I needed : but I don't understand the difference between percent, max, min*

=====================
service.command.jt.heapsize.percent=10
service.command.jt.heapsize.max=5000
service.command.jt.heapsize.min=256

===========================
Any recommendations on how to set these properties for 48GB RAM

Also, Where I can set mapred.map.child.java.opts if I have to increase the Child Heap size ( mapred-ste.xml might be one place wondering if we have any other files)
