Amareshwari Sriramadasu resolved MAPREDUCE-81.

    Resolution: Duplicate

> missing userlogs
> ----------------
>                 Key: MAPREDUCE-81
>                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-81
>             Project: Hadoop Map/Reduce
>          Issue Type: Bug
>            Reporter: Christian Kunz
> I noticed that a long-running job taking more than 1 day can have reduce tasks with missing
stderr and stdout log directories (the syslog files exist).
> I wonder whether it has to do with the default value of 12 hours for mapred.userlog.retain.hours,
resulting in deletion of the stderr/stdout directories for reduce tasks idling till they start
to actually reduce.
