I quickly went through the code, In ExecutorBackend, we build the actor system with
// Create SparkEnv using properties we fetched from the driver. val driverConf = new SparkConf().setAll(props) val env = SparkEnv.createExecutorEnv( driverConf, executorId, hostname, port, cores, isLocal = false) props is the spark properties fetched from driver, In Driver side, we start driver actor with val properties = new ArrayBuffer[(String, String)] for ((key, value) <- scheduler.sc.conf.getAll) { if (key.startsWith("spark.")) { properties += ((key, value)) } } // TODO (prashant) send conf instead of properties driverActor = actorSystem.actorOf( Props(new DriverActor(properties)), name = CoarseGrainedSchedulerBackend.ACTOR_NAME) This “properties” is the stuff being sent to executor. It seems that we only admit the properties starting with “spark.” It seems that we cannot pass akka.* to executor? Hi, Josh, would you mind giving some hints, as you created and closed the JIRA?
