Description

Jobtracker store 1.jar file and 1 .xml per job in /srv/hadoop/var/mapred/local/jobTracker.

They seems to be correctly delete in most cases BUT not when a job is launch with
Map total: 0 and Reduce total: 0
This happen when the job doesn't find any input file to process.

After few months, lots of disk space is lost because of that.

This issue is different from HADOOP-2427 since it's on the jobtracker, not on the nodes, but it may be related in some way in the code (my 2 cents).
