<jobOutputDir> is the location specified by the configuration property
"hadoop.job.history.user.location". If you don't specify anything for the property,
the job history logs will be created in job's output directory. So, to view your history give
your jobOutputDir, if you havent specified any location.
Hope this helps.
Thanks

I am having trouble getting the hadoop command "job -hisotry" to work. What
am I suppose to use for <jobOutputDir>? I can see the job history from the
JobTracker web ui. I tried specifing the history directory on the

$ hadoop job -history logs/history/
