what is the difference between two downloadable versions of giraph: 1.2giraph-dist-1.2.0-hadoop2-bin.tar.gz and giraph-dist-1.2.0-bin.tar.gz

Question

What is the difference between giraph-dist-1.2.0-hadoop2-bin.tar.gz and giraph-dist-1.2.0-bin.tar.gz. Is there any documentation about that?

The only documentation that I found is the following one:

• Apache Hadoop 2 (latest version: 2.5.1)

  This is the latest version of Hadoop 2 (supporting YARN in addition to MapReduce) Giraph could use. You may tell maven to use this version with "mvn -Phadoop_2 ".
