    Description

      We have had a spate of questions about memory usage of hadoop daemons and Map-Reduce jobs and how to configure them.

      We should better document mapred.child.java.opts in the Map-Reduce tutorial and cluser_setup.html and link to http://hadoop.apache.org/core/docs/r0.15.3/cluster_setup.html#Configuring+the+Environment+of+the+Hadoop+Daemons.
