I'm trying to set a System Property in the Hadoop config, so my jobs will know which cluster they are running on. I think I should be able to do this with -Dname=value in "mapred.child.java.opts" (example below), but the setting is ignored. In hadoop-site.xml I have: <property> <name>mapred.child.java.opts</name> <value>-Xmx200m -Dfoo=test</value> </property> But the job conf through the web server indicates: mapred.child.java.opts -Xmx1024M -Duser.timezone=UTC
I'm using Hadoop-0.17.2.1. Any tips on why my setting is not picked up?
