Job log location and retention
Dear all,
I would like to ask why the logs (configurations and status) of my job
disappeared in the Jobtracker web UI?
Specifically, I finished a job four days ago, but I cannot find it in the
Jobtracker web UI, neither in the
homepage nor "Job Tracker History" on the left-bottom corner.
The cluster is deployed with CDH3, and users actively submit jobs.
Some configurations:
*mapred.jobtracker.retirejob.interval*3600000
*mapred.jobtracker.completeuserjobs.maximum*5
Thank you very much.
Regards,
Zheyi Rong

Thank you for the answer.
However, I do not have the access to the jobtracker's local system...
Fortunately I have found a workaround -- using
$hadoop job -history [output]

Zheyi.

Zheyi,
The jobtracker doesn't keep a reference to the job to save memory, but you may still find it in the filesystem. For a default CDH3 installation, it will be in the jobtracker's local filesystem, at /var/log/hadoop-0.20/history/done/
Logs from individual tasks are a little trickier to find. They will be in the node that ran that task, at /var/log/hadoop-0.20/history/userlogs if they haven't been deleted yet -- deletion is controled by mapreduce.job.userlog.retain.hours, and the default is 24 hours.
