I’ve had a look at the assembled giraph-core jar file and it does not contain any GiraphYarnTask. How so?
Running my application using the GiraphRunner works fine as long as I only have one worker (local mode). To use the other workers, I need to start MR TaskTrackers on the machines - which aren’t available on hadoop 2.5.1. Thats why I need the GiraphYarnTask.
