Hi -- I just do single machine and typically use the grateful-dead dataset.
However, for Hadoop and Spark, make sure you have multiple workers so you test
worker communication as that is where the jar issues usually make themselves
apparent --- netty, jetty, javax-servelt... those are usually the culprits.
