Giraph Formats Tests broken

GIRAPH-209 broke giraph-formats-contrib tests because of the prop.jarLocation change.

In giraph-formats-contrib/pom.xml we have prop.jarLocation set as:
<property>
<name>prop.jarLocation</name>
<value>${giraph.trunk.base}/target/giraph-${project.version}-jar-with-dependencies.jar</value>
</property>

The problem is I don't see how to easily get the hadoop version (until maybe we have the parent pom which can hold the version for everyone to use). Eli, assigning this to you for your thoughts.

Note that when I changed this value by hand to ${giraph.trunk.base}/target/giraph-${project.version}-for-hadoop-0.20.203.0-jar-with-dependencies.jar the tests run. Something is still failing but it is a completely different reason, not because of System.getProperty("prop.jarLocation") problems.
