fixed the jar problem with Giraph -- /Users/marko/software/tinkerpop/tinkerpop3/giraph-gremlin/target/giraph-gremlin-3.0.0-SNAPSHOT-standalone required. That then grabs all the .jars in the lib/ directory and puts them in Hadoops DistributedCache. this model is pretty cool in that if you have other jars you want, you simply drop them in there and it will be picked up.
