Amar Kamat updated MAPREDUCE-1422:
----------------------------------
Attachment: mapreduce-1422-v1.4.2.patch
Attaching a patch for review. Changes are as follows
- Added a hook in task-controller.c for enabling job cleanup.
- Modified TestTaskTrackerLocalization to check if the default task-controller
deletes job-local-dir with files in it such that the task-tracker doesn't have
delete permissions.
- Added a new testcase (TestJobLocalDirCleanupWithLinuxTaskController) to check
the above mentioned scenario with LinuxTaskController.
- Modified the framework to support job-local-dir cleanup
test-patch passed. All tests except the following passed :
- TestMiniMRLocalFS
- TestTTResourceReporting
- TestTrackerDistributedCacheManager
- TestFileArgs
- TestSimulatorEndToEnd
- TestSimulatorJobTracker
- TestSimulatorSerialJobSubmission
- TestSimulatorStressJobSubmission
All the above failed on trunk too.

>
> 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.
