> 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.
