Subject [jira] Commented: (MAPREDUCE-927) Cleanup of task-logs should happen in TaskTracker instead of the Child
Date Fri, 16 Oct 2009 04:57:31 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-927?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12766412#action_12766412

Amareshwari Sriramadasu commented on MAPREDUCE-927:
---------------------------------------------------

I'm just thinking that mapred.task.userlog.retain.hours is not a job-level parameter. It should
be TaskTracker's parameter and TaskTracker should cleanup the logs after mapred.task.userlog.retain.hours
after the job completion.

> Task logs' cleanup is being done in Child now. This is undesirable atleast for two reasons:
1) failures while cleaning up will affect the user's tasks, and 2) the task's wall time will
get affected due to operations that TT actually should own.
