      Allow logging level of map/reduce tasks to be configurable. Configuration changes:   add mapred.map.child.log.level   add mapred.reduce.child.log.level

    Description

      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.
