I use Eclipse and it's okay for running unittests, but I need to set the VM args in the junit run configuration for each specific test to -Dprop.jarLocation=target/giraph-0.70-jar-with-dependencies.jar. I assume you need to do the same for Intellij.

This is done in pom.xml when doing 'mvn test' and other mvn commands.
