Spark Runtime Error - ClassDefNotFound: SparkConf

Question

After installing and building Apache Spark (albeit with quite a few warnings), the compilation of our Spark application (using "sbt package") completes successfully. However, when trying to run our application using the spark-submit script, a runtime error results that states that the SparkConf class definition was not found. The SparkConf.scala file is present on our system, but it seems as if it is not being built correctly. Any ideas on how to solve this?

resolvers += "clojars" at "https://clojars.org/repo"

What are your CLASSPATH and SPARK_HOME environment variables set to? Also, there are errors and warnings further up in the output saying that /opt/Spark/spark-1.4.0/jars/elasticsearch-hadoop-2.1.0.Beta2.jar is missing. Have you checked that? I realize getting the NoClassDefFoundError: org/apache/spark/SparkConf wouldn't be expected, but putting that jar in the right place would eliminate a potential cause especially considering that the error seems to be getting generated within a class in that jar. — DemetriKots, Jul 01 '15 at 23:52
The PATH variable is set to: /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/opt/Scala/scala-2.11.6/bin:/opt/Spark/spark-1.4.0 and SPARK_HOME is set to: /opt/Spark/spark-1.4.0 As far as I know, the elasticsearch-hadoop jar is not necessary because it is included in the dependencies and is installed on the machine. Running it without the --jars produces the same error. — kgrimes2, Jul 02 '15 at 16:03

Is spark JAR inside the JAR you submitting ? it seems that you tell sbt you're providing the jar but i don't see "unmanagedJars in Compile += file(...)" in you're sbt, if you're counting that the jar are in the machine i would suggest you wouldn't do that since it mat lead to this kind of problems.

Try unrar you're JAR and see if spark JAR are there, if not use sbt-assembly or other tool of you're choice.

The elasticsearch-hadoop jar does not exist, but it is included in the dependencies. The same error is produced by running it without the --jars. I have tried using sbt-assembly tool, but that produces errors as well. – kgrimes2 Jul 02 '15 at 16:07
Even with sbt assembly the jar aren't inside you're jar ? – user1120007 Jul 02 '15 at 21:13

Don't use provided scope as it makes the dependencies available only while compiling and not while running the code. Changed code look like..

libraryDependencies ++= Seq(
    "org.apache.spark" %% "spark-core" % "1.4.0",
    "org.apache.spark" %% "spark-streaming" % "1.4.0",
    "org.apache.spark" %% "spark-sql" % "1.4.0",
    "org.elasticsearch" % "elasticsearch-hadoop" % "2.1.0.Beta2" exclude("org.spark-project.akka", "akka-remote_2.10") exclude("org.spark-project.akka", "akka-slf4j_2.10") exclude("org.json4s", "json4s-ast_2.10") exclude("org.apache.spark", "spark-catalyst_2.10") exclude("com.twitter", "chill_2.10") exclude("org.apache.spark", "spark-sql_2.10") exclude("org.json4s", "json4s-jackson_2.10") exclude("org.json4s", "json4s-core_2.10") exclude("org.apache.spark", "spark-core_2.10")
  )
