Problem with scala version mismatch in Spark application

I was developing a spark program on my machine and it worked ok. But when i tried to deploy it in Spark running in my Hadoop sandbox i started getting this error

java.lang.NoSuchMethodError: scala.runtime.IntRef.create(I)Lscala/runtime/IntRef;

So it seems the problem is you need to use same version of Scala for compiling your code as the Scala used by Spark. In my case i was using scala 2.11 for compiling my code and Spark 1.3.1 uses Scala 2.10.4. So i changed the build file and then rebuilt the code and deployed it. That fixed the issue
