Shared files in Hadoop MR cluster

Hi,

In hadoop MR exists the property "mapred.system.dir" to set a relative
directory where shared files are stored during a job run. What are
these shared files?

AFAIK, a Job's JobInfo representation is saved inside a job directory
under mapred.system.dir (actually, it is more a JobTracker's system
directory than others'), along with a job.jar for job recovery
purposes.
