Subject [jira] Commented: (MAPREDUCE-1100) User's task-logs filling up local disks on the TaskTrackers
Date Sat, 04 Dec 2010 00:24:14 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-1100?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12966752#action_12966752

Todd Lipcon commented on MAPREDUCE-1100:
----------------------------------------

Before this is committed to trunk, it will also need to be updated to use SecureIOUtils to
open the logs for truncation (see the 0.20 patch for MAPREDUCE-2096)

> 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.
