Hi,
I am trying to run a program with spark streaming using Kafka on a stand
alone system. These are my details:
Spark 1.0.0 hadoop2
Scala 2.10.3
I am trying a simple program using my custom sbt project but this is the
error I am getting:
Exception in thread "main" java.lang.NoClassDefFoundError:

here is my .sbt file:
name := "Simple Project"
version := "1.0"
scalaVersion := "2.10.3"
libraryDependencies += "org.apache.spark" %% "spark-core" % "1.0.0"
libraryDependencies += "org.apache.spark" %% "spark-streaming" % "1.0.0"
libraryDependencies += "org.apache.spark" %% "spark-sql" % "1.0.0"

libraryDependencies += "org.apache.spark" % "spark-streaming-kafka_2.10"

resolvers += "Akka Repository" at "http://repo.akka.io/releases/";
resolvers += "Maven Repository" at "http://central.maven.org/maven2/";
sbt package was successful. I also tried sbt "++2.10.3 package" to build
it for my scala version. Problem remains the same.
Can anyone help me out here? Ive been stuck on this for quite some time now.
Thank You,
Dilip
