Akka error: play framework (2.3.3) and spark (1.0.2)

Question

I am trying to connect to Spark from the Play framework. Getting the following Akka error ...

ERROR] [08/16/2014 17:12:05.249] [spark-akka.actor.default-dispatcher-3] [ActorSystem(spark)] Uncaught fatal error from thread [spark-akka.actor.default-dispatcher-3] shutting down ActorSystem [spark] java.lang.AbstractMethodError at akka.actor.dungeon.FaultHandling$class.akka$actor$dungeon$FaultHandling$$finishTerminate(FaultHandling.scala:210) at akka.actor.dungeon.FaultHandling$class.terminate(FaultHandling.scala:172) at akka.actor.ActorCell.terminate(ActorCell.scala:369) at akka.actor.ActorCell.invokeAll$1(ActorCell.scala:462) at akka.actor.ActorCell.systemInvoke(ActorCell.scala:478) at akka.dispatch.Mailbox.processAllSystemMessages(Mailbox.scala:263) at akka.dispatch.Mailbox.run(Mailbox.scala:219) at akka.dispatch.ForkJoinExecutorConfigurator$AkkaForkJoinTask.exec(AbstractDispatcher.scala:393) 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)

I also found this thread that mentions Akka compatibility. How to run Play 2.2.x using Akka 2.3.x?

any suggestions?

thanks!

Answer 1

(answering my question if others are looking for a solution)

This is caused by Akka library mismatch. Akka versions 2.2 and 2.3 are not compatible with binary

spark (v1.0.0, v1.0.2) uses: akka 2.2.3-shaded-protobuf

The playback structure uses the following play v2.2.0, v2.2.2, v2.2.3 uses akka 2.2.0 play v2.3.3 uses akka 2.3.4

In my case, I used play 2.2.3 with Spark 1.0.2
