Confused about how to train MLP in distributed way in mahout

[gongjuntai]

Hi,

I'm new to mahout. I want to know how to train MLP in distributed way with 
batch gradient descent in mahout just like 
https://issues.apache.org/jira/browse/MAHOUT-1265 describes.
An example will be very helpful. 

Thanks.
