I have the same issue running giraph built with -Phadoop_yarn -Dhadoop.version=2.2.0 on Hortonworks. I get classnotfoundexceptions, looks like the GiraphRunner may not be able to load the classes correctly while running on Yarn. So if anybody has had success please share your experience, wondering what I have been doing wrong.
