> HADOOP-1274 replaced the configuration attribute
> mapred.tasktracker.tasks.maximum with mapred.tasktracker.map.tasks.maximum
> and mapred.tasktracker.reduce.tasks.maximum and claims to use the deprecated
> mapred.tasktracker.tasks.maximum. However, because the new attributes are in
> hadoop-default.xml, the check to use the deprecated value will never trigger.
