> Key: MAPREDUCE-1607

> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: task-controller
> Reporter: Hemanth Yamijala
> Assignee: Amareshwari Sriramadasu
>
> Task controller uses the INITIALIZE_TASK command to initialize task attempt
> and task log directories. For cleanup tasks, task attempt directories are
> named as task-attempt-id.cleanup. But log directories do not have the
> .cleanup suffix. The task controller is not aware of this distinction and
> tries to set permissions for log directories named task-attempt-id.cleanup.
> This is a NO-OP. Typically the task cleanup runs on the same node that ran
> the original task attempt as well. So, the task log directories are already
> properly initialized. However, the task cleanup can run on a node that has
> not run the original task attempt. In that case, the initialization would not
> happen and this could result in the cleanup task failing.
