PJ Fanning updated SPARK-8494:
------------------------------
Description:
I found a similar issue to SPARK-1923 but with Scala 2.10.4.
I used the Test.scala from SPARK-1923 but used the libraryDependencies from a
build.sbt that I am working on.
If I remove the spray 1.3.3 jars, the test case passes but has a
Application:
{code}
import org.apache.spark.SparkConf
import org.apache.spark.SparkContext
object Test {
def main(args: Array[String]): Unit = {
val conf = new SparkConf().setMaster("local[4]").setAppName("Test")
val sc = new SparkContext(conf)
sc.makeRDD(1 to 1000, 10).map(x => Some(x)).count
sc.stop()
}
{code}
Exception:
{code}

I just wanted to document this for posterity. I had an issue when running a
Spark 1.0 app locally with sbt. The issue was that if you both:
1. Reference a scala class (e.g. None) inside of a closure.
2. Run your program with 'sbt run'
It throws an exception. Upgrading the scalaVersion to 2.10.4 in sbt solved this
issue. Somehow scala classes were not being loaded correctly inside of the
executors:
Application:
{code}
import org.apache.spark.SparkConf
import org.apache.spark.SparkContext
object Test {
def main(args: Array[String]): Unit = {
val conf = new SparkConf().setMaster("local[4]").setAppName("Test")
val sc = new SparkContext(conf)
sc.makeRDD(1 to 1000, 10).map(x => Some(x)).count
sc.stop()
}
{code}
Exception:
