> On one of our 0.23 clusters, I saw a case of two containers, corresponding to two map tasks of a MR job, that were launched almost simultaneously on the same node.  It appears they both tried to localize job.jar and job.xml at the same time.  One of the containers failed when it couldn't rename the temporary job.jar directory to its final name because the target directory wasn't empty.  Shortly afterwards the second container failed because job.xml could not be found, presumably because the first container removed it when it cleaned up.
