Exception in thread "pool-10-thread-2" java.lang.NoSuchMethodError: akka.actor.ActorSystem.dispatcher()Lscala/concurrent/ExecutionContext; It worked locally in my Intellij but failed when I launch it from Spark-submit. Google suggested it's a compatibility issue in Akka. And I'm using latest Spark built from the HEAD, so the Akka used in Spark-submit is 2.3.4-spark. I tried both Spray 1.3.2 (built for Akka 2.3.6) and 1.3.1 (built for 2.3.4). Both failed with the same exception. Anyone has idea what went wrong?
