Re: How to set System property for my job

[mlimotte <ms...@gmail.com>]

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/@taskid@.gc
     -Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.ssl=false
  </value>
</property>
