I get the same error when I compile Giraph against the default hadoop version (0.20.203.0), but my project that uses Giraph uses a more recent hadoop version. Did you set the hadoop version via a maven profile when compiling Giraph (e.g. mvn -Phadoop_1.0 compile for hadoop 1.0)?
Presumably, there's a way to compile Giraph for Yarn. There's even a Yarn profile in the pom.xml. I personally haven't had success building it though.
