Thanks Jens

I Refereed Apache Mahout <http://mahout.apache.org/>

6 Feb 2012 - Apache Mahout 0.6 released
Apache Mahout has reached version 0.6. All developers are encouraged
to begin using version 0.6. Highlights include:
Improved Decision Tree performance and added support for regression problems

I downloaded Apache mahout:

1. Whether "df" is the implementation of decision tree?

Some of the documents tell that it is not Decision tree but Random forest

What is it actually?
