mapred/local/jobTracker is not cleanup correctly
------------------------------------------------
Key: HADOOP-2517
URL: https://issues.apache.org/jira/browse/HADOOP-2517
Project: Hadoop
Issue Type: Bug
Components: mapred
Affects Versions: 0.14.0
Reporter: Benjamin Francisoud
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).
