---------------------------------------

No new checkstyle issue is been introduced and since its javadoc updation and correction at default value no need of testcase.
Please review the patch

> 1.
> As per mapred-default.xml , default value for number of map task per job is 2, but in JobConf#getNumMapTasks() it is 1
> {noformat}
>   <name>mapreduce.job.maps</name>
>   <value>2</value>
> {noformat}
> 2. Javadoc for getNumMapTasks() is misleading, as it explains about number of reduce task
> {code}
>   /**
>    * Get configured the number of reduce tasks for this job.
>    * Defaults to <code>1</code>.
>    * 
>    * @return the number of reduce tasks for this job.
>    */
>   public int getNumMapTasks() { return getInt(JobContext.NUM_MAPS, 1); }
> {code}
