Subject [jira] [Commented] (MAPREDUCE-1100) User's task-logs filling up local disks on the TaskTrackers
Date Thu, 24 Nov 2011 01:52:43 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-1100?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13156464#comment-13156464
] 

Arun C Murthy commented on MAPREDUCE-1100:
------------------------------------------

Konstantin/Milind - I'd strongly urge you to consider this 0.22. Without this patch, and with
a simple cron job, debugging user jobs becomes very hard and leads to lots of angst.

> Some user's jobs are filling up TT disks by outrageous logging. mapreduce.task.userlog.limit.kb
is not enabled on the cluster. Disks are getting filled up before task-log cleanup via mapred.task.userlog.retain.hours
can kick in.
