> Key: MAPREDUCE-1422
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-1422
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: tasktracker
> Reporter: Ravi Gummadi
> Assignee: Amar Kamat
> Attachments: mapreduce-1422-v1.4.2.patch
>
>
> After MAPREDUCE-896, if LinuxTaskController is set in config, task-controller
> binary is launched for changing permissions of taskAttemptDir and taskWorkDir
> before cleaning up of these directories sothat cleanup will be succeeded even
> if user had created files/dirs under taskAttemptDir or taskWorkDir with
> non-writable permissions. Users can't create files/dirs under job-dir
> directly as we set 2570 for job-dir. But as job-work-dir has 2770 permissions
> and user can create files/dirs under job-work-dir with non-writable
> permissions, Changing permissions of files/dirs under job-work-dir may be
> needed sothat cleaning up of job-dir in all mapred-local-directories succeeds
> always.
