Task controller may not set permissions for a task cleanup attempt's log
directory
----------------------------------------------------------------------------------
Key: MAPREDUCE-1607
URL: https://issues.apache.org/jira/browse/MAPREDUCE-1607
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: task-controller
Reporter: Hemanth Yamijala
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.
