[jira] Created: (HADOOP-5786) The logging level of the tasks should be configurable by the job

The logging level of the tasks should be configurable by the job
----------------------------------------------------------------

                 Key: HADOOP-5786
                 URL: https://issues.apache.org/jira/browse/HADOOP-5786
             Project: Hadoop Core
          Issue Type: Improvement
          Components: mapred
            Reporter: Owen O'Malley


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.

[jira] Commented: (HADOOP-5786) The logging level of the tasks should be configurable by the job

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.
