I have a standalone spark cluster and from within the same scala application I'm creating 2 different spark context to run two different spark streaming jobs as SparkConf is different for each of them.
I'm getting this error that... I don't really understand: 14/09/16 11:51:35 ERROR OneForOneStrategy: spark.httpBroadcast.uri > java.util.NoSuchElementException: spark.httpBroadcast.uri > at org.apache.spark.SparkConf$$anonfun$get$1.apply(SparkConf.scala:149) > at org.apache.spark.SparkConf$$anonfun$get$1.apply(SparkConf.scala:149) > at scala.collection.MapLike$class.getOrElse(MapLike.scala:128) > at scala.collection.AbstractMap.getOrElse(Map.scala:58) > at org.apache.spark.SparkConf.get(SparkConf.scala:149) > at > org.apache.spark.broadcast.HttpBroadcast$.initialize(HttpBroadcast.scala:130) > at > org.apache.spark.broadcast.HttpBroadcastFactory.initialize(HttpBroadcastFactory.scala:31) > at > org.apache.spark.broadcast.BroadcastManager.initialize(BroadcastManager.scala:48) > at > org.apache.spark.broadcast.BroadcastManager.<init>(BroadcastManager.scala:35) > at org.apache.spark.SparkEnv$.create(SparkEnv.scala:218) > at org.apache.spark.executor.Executor.<init>(Executor.scala:85) > at > org.apache.spark.executor.CoarseGrainedExecutorBackend$$anonfun$receive$1.applyOrElse(CoarseGrainedExecutorBackend.scala:59) > at akka.actor.ActorCell.receiveMessage(ActorCell.scala:498) > at akka.actor.ActorCell.invoke(ActorCell.scala:456) > at akka.dispatch.Mailbox.processMailbox(Mailbox.scala:237) > at akka.dispatch.Mailbox.run(Mailbox.scala:219) > at > akka.dispatch.ForkJoinExecutorConfigurator$AkkaForkJoinTask.exec(AbstractDispatcher.scala:386) > at scala.concurrent.forkjoin.ForkJoinTask.doExec(ForkJoinTask.java:260) > at > scala.concurrent.forkjoin.ForkJoinPool$WorkQueue.runTask(ForkJoinPool.java:1339) > at > scala.concurrent.forkjoin.ForkJoinPool.runWorker(ForkJoinPool.java:1979) > at > scala.concurrent.forkjoin.ForkJoinWorkerThread.run(ForkJoinWorkerThread.java:107) > 14/09/16 11:51:35 ERROR CoarseGrainedExecutorBackend: Slave registration > failed: Duplicate executor ID: 10 > > Both apps has different names so I don't get how the executor ID is not unique :-S This happens on startup and most of the time only one job dies, but sometimes both of them die.
