Just checked it with 1.0.2 Still same exception. From: Anton Brazhnyk [mailto:anton.brazh...@genesys.com] Sent: Wednesday, August 27, 2014 6:46 PM To: Tathagata Das Cc: user@spark.apache.org Subject: RE: [Streaming] Akka-based receiver with messages defined in uploaded jar
Sorry for the delay with answer – was on vacation. As I said I was using modified version of launcher from the example. Modification is just about setting spark master URL in the code to not use run-example script. The launcher itself was in the attached zip (attaching it once more) as ActorWordCount object.

Using spark-submit? Or some other script (can you provide that)?

The reason could very well be what you suggest, but I want to understand what conditions lead to this.
