Spark isn't loading, what's up with that? - scala

Question

So the problem that I am having is that I don't seem to be able to create a sparkcontext. And I have no idea why not.
Here is my code:
import org.apache.spark.{SparkConf, SparkContext}
object spark_test{
def main(args: Array[String]): Unit = {
val conf = new SparkConf().setAppName("Datasets Test").setMaster("local")
val sc= new SparkContext(conf)
println(sc)
}
}
And here is the result that I am getting:
Exception in thread "main" java.lang.NoSuchMethodError: scala.Predef$.refArrayOps([Ljava/lang/Object;)Lscala/collection/mutable/ArrayOps;
at org.apache.spark.SparkConf.getAkkaConf(SparkConf.scala:203)

Any thoughts?

Answer 1

Your scala version is too new and spark-core version is too old . I am using scala 2.11.8 and spark-core_2.11:2.0.1，you can try it!
