Is there any reason you actually *need* Giraph to run on YARN?
If you don't get any benefit out of it -- just go with the default MR model.

For what I could learn, Yarn is the result a of a complete overhaul of MR, so I thought I
could be wise to focus on the new technology: should I rollback to Hadoop_2 profile instead
of pure_yarn? Or am I just missing the whole picture?
