IOException: job.xml already exists
-----------------------------------
Key: HADOOP-705
URL: http://issues.apache.org/jira/browse/HADOOP-705
Project: Hadoop
Issue Type: Bug
Components: mapred
Affects Versions: 0.8.0
Reporter: Nigel Daley
Assigned To: Mahadev konar
I'm seeing this exception in the JobTracker log. It's caused the same map to
fail enough that the job aborted.
