this works for h2o standalone maprfs ..it adds -Djava.library.path=/opt/mapr/lib to the java -jar for h2o, but the one I'm using is from pre mapr 3.0.1 ..I think it has a JNI jar that might be missing in the latest mapr stuff. Our mapr is 3.0.1 and this test correctly talks to it using the old /opt/mapr/lib
