hadoop  have a lot of config property. People will make mistake when modify configuration file. So hadoop can do config check tool .This tool can find mistake as follow.
if config 
<property>
	  <name>mapreduce.tasktracker.reduce.tasks.maximu</name> <!--should be mapreduce.tasktracker.reduce.tasks.maximum-->
	  <value>9</value>
	  <description>The maximum number of reduce tasks that will be run
	  simultaneously by a task tracker.
	  </description>
	</property>

OR this tool can warn use deprecated property name and correct it.
