> We run hadoop/hdfs under a generic username of 'hadoop'.  When submitting a job as user 'fred', the job.xml file gets created correctly as /tmp/*hadoop-fred*/mapred/system/<job_id>/job.xml, but the JobInProgress constructor appears to use the incorrect path of /tmp/*hadoop-hadoop*/mapred/system/<job_id>/job.xml for the copyToLocalFile operation.  This results in an exception because the job.xml file does not exist under /tmp/hadoop-hadoop.
> I think the incorrect path gets created on line 133 in JobInProgress.java right before the call to copyToLocalFile.  If I hardcode the correct path (just to test my theory) of "/tmp/hadoop-fred/mapred/system" in place of the call to default_conf.getSystemDir(), the job kicks off and runs to completion as the user 'fred' with hadoop/hdfs running as the user 'hadoop'.
> Here's a portion of the output when the job is submitted by user 'fred':
> [fred@hdm01 ~]$ hadoop --config /usr/local/hadoop/conf jar /usr/local/hadoop/current/hadoop-0.14.1-examples.jar wordcount mytest/input/data output2
> 07/10/07 17:52:14 INFO mapred.FileInputFormat: Total input paths to process : 62
