Unfortunately the s4-benchmarks were not completely updated with the latest API changes. If you can file a jira ticket we'll update that.
Changes include: 1/ "Main" -> "S4Node" in startNode.sh and startInjector.sh 3/ in the bench-cluster.sh script, configure app class for injector cluster before starting the injector nodes, instead of passing that when starting injectors (i.e. do a "s4 deploy" with the correct args instead of passing them to the startInjector.sh scripts) It's not too difficult to change so you may give it a try. Otherwise we'll fix that from a jira ticket.
