Increasing Mapper/Reducer memory

Hi,

I need to increase the mapper/reducer memory:

mapred.map.child.java.opts

Where exactly do I do that ?  Do I have to change the code in a java file
and rebuild ?  or is there a conf file that I can alter ?

Thanks,

You can specify it on the command line

-Dmapred.map.child.java-opts

or in conf/mapred-site.xml
