Subject [jira] Commented: (HADOOP-5786) The logging level of the tasks should be configurable by the job
Date Fri, 08 May 2009 10:53:45 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-5786?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12707307#action_12707307

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.

> 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.
