I think what you want is the section "Task Execution & Environment" in
http://hadoop.apache.org/core/docs/current/mapred_tutorial.html
http://hadoop.apache.org/core/docs/current/mapred_tutorial.html . Here is a
sample from that document:
<property>
<name>mapred.child.java.opts</name>
<value>
-Xmx512M -Djava.library.path=/home/mycompany/lib -verbose:gc
-Xloggc:/tmp/@[email protected]
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.ssl=false
</value>
</property>
