> 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.
