Description

The jobtracker is treating the file 'jobtracker.info' in the system data directory as a job to be recovered, resulting in the following:

10/09/09 18:06:02 WARN mapred.JobTracker: Failed to add the job jobtracker.info
java.lang.IllegalArgumentException: JobId string : jobtracker.info is not properly formed
