Hong Tang commented on HADOOP-5786:
-----------------------------------
With regard to storage consumption of logs, we could separate debug/info
logging from warn/error logging, and employ log rotation on the former. This
would prevent disk exhaustion even if debug/info are not disabled.
> The logging level of the tasks should be configurable by the job

> It would be nice to be able to configure the logging level of the Task JVM's
> separately from the server JVM's. Reducing logging substantially increases
> performance and reduces the consumption of local disk on the task trackers.
