Which version of hadoop are you using? Changing ‘mapreduce.jobtracker.staging.root.dir’ in mapred-site.xml should work. Did you restart the jobtracker after making the change? With the latest version of hadoop on trunk, there is also ‘yarn.app.mapreduce.staging-dir’ in yarn-site.xml

I read someone else set mapreduce.jobtracker.staging.root.dir, but I have had no luck with this (or slightly different versions of it) in my config files. I'm guessing this other user set it in their code? How would I do that if I run a command like, "hadoop jar /usr/lib/hadoop/hadoop-*-examples.jar pi 2 100000"? My preference though would be to overwrite this setting in the config files so that every user wouldn't have to specify it (i.e. assuming I don't let them use the temp folder).
