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.

Hi Duanyu,

Can you provide more information, such as the code, the Azkaban link, and what 
you’re using to log information?

We also have office hours at 2pm today.

Thanks,

Edwina

Subject: modify the MapTask.java but no change

Hi,

I modify the MapTask.java file in order to output more log information. I 
re-compile the file and deploy the jar to the whole clusters, but I  found that 
the output log has not changed, I don't know why.

Hi,

I modify the MapTask.java file in order to output more log information. I
re-compile the file and deploy the jar to the whole clusters, but I  found
that the output log has not changed, I don't know why.
