> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: tasktracker
> Affects Versions: 0.22.0
> Reporter: Amareshwari Sriramadasu
> Assignee: Amareshwari Sriramadasu
> Fix For: 0.22.0

>
> Currently TaskTracker.lcoalizeJob sets permissions (570 with
> LinuxTaskController) on job log directory recursively. When the tracker
> restarts/reinits, if there are new tasks for the job, localizeJob would find
> attempt log directories for the earlier tasks. If the job has many tasks, it
> would spend significant time in chmod'ing.
> Also, if a cleanup attempt is launched after the restart/reinit, we would hit
> MAPREDUCE-1607.
