Amareshwari Sriramadasu updated MAPREDUCE-1607: ----------------------------------------------- Status: Patch Available (was: Open) All linux task controller tests passed with the patch (both as tt user and some other user). I tested viewing of task logs and cleanup attempts logs on the single node machine. > 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 > Assignee: Amareshwari Sriramadasu > Attachments: patch-1607-1.txt, patch-1607-ydist.txt, patch-1607.txt > > > 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. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
