Subject [jira] Commented: (HADOOP-1642) Jobs using LocalJobRunner + JobControl fails
Date Mon, 12 Nov 2007 10:08:51 GMT

Adrian Woodhead commented on HADOOP-1642:
-----------------------------------------

Yes, the original fix is indeed in the trunk, the patch I have submitted was also built against
the trunk and requires Doug's original patch and should be applied in addition to it as it
solves the second issue which arose after the original patch. Can someone please code review
it and see if it is acceptable?

> If I run several jobs at the same time using JobControl and the LocalJobRunner i get:
> java.io.IOException: Target /tmp/hadoop-johan/mapred/local/localRunner/job_local_1.xml
already exists.
> It seems like the JobControl class tries to run multiple jobs with the same jobid, causing
the exception.
