Subject [jira] Commented: (HADOOP-4491) Per-job local data on the TaskTracker node should have right access-control
Date Wed, 05 Aug 2009 09:37:14 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-4491?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12739393#action_12739393
] 

Hemanth Yamijala commented on HADOOP-4491:
------------------------------------------

Some comments on the task-controller code:

- Code in run_task_as_user can reuse code from initialize_task
- I think test-task-controller can be moved to a test folder following convention from other
C++ modules.
- The log file for the taskcontroller in open_log_file should be closed if we can't change
permissions to it.
- When there's an error in initializing job for any of the m/r local dirs, we should free
the job_dir parameter, right ? Similarly in initializing task.
- Task log dir for cleanup tasks will not have the name task-attempt-id.cleanup. This seems
fine right now. Because we check if the directory exists and return if it doesn't. Can we
comment this ?
- Variable jars_dir not being used in run_task_as_user.
- job_dir needs to be freed before execlp
