Subject Re: modify the MapTask.java but no change

Hi DuanYu!

Most likely, the MapTask class loaded is not from your jar file. Here's a
look at how Oracle JAVA loads classes :
http://docs.oracle.com/javase/8/docs/technotes/tools/findingclasses.html .
Check the classpath that your MapTask is started with.
