How do I set mapred.map.child.java.opts in my mapred-site.xml

currently I tried to add -Xmx2048m to already existing values like  <name>mapred.map.child.java.opts</name>
  <value>-Xmx2048m -XX:ErrorFile=/opt/cores/mapreduce_java_error%p.log</value>
 but it is not picking the change even after restarting the jobtracker

any ideas

also wondering if any maprcli command to restart the JT
