Description

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.

Sub-Tasks

• Cleanup of task-logs should happen in TaskTracker instead of the Child: Closed
• Truncate logs of finished tasks to prevent node thrash due to excessive logging: Resolved
