[jira] [Comment Edited] (SPARK-8494) ClassNotFoundException when
running with sbt, scala 2.10.4, spray 1.3.3
[ https://issues.apache.org/jira/browse/SPARK-8494?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15544436#comment-15544436 ]

Hello Experts,
I am facing similar error while trying to run my Spark ML code. In my case, the error is thrown while trying to load the saved CrossValidatorModel from the filesystem.
Background: I am trying to expose a scala code as a REST service through Scalatra. The flow is to load the model, and use it to predict the class for an user input.
ERROR org.apache.spark.util.Utils - Exception encountered java.lang.ClassNotFoundException: scala.Some at java.net.URLClassLoader$1.run(URLClassLoader.java:372) ~[na:1.8.0_25] at java.net.URLClassLoader$1.run(URLClassLoader.java:361) ~[na:1.8.0_25] at java.security.AccessController.doPrivileged(Native Method) ~[na:1.8.0_25] at java.net.URLClassLoader.findClass(URLClassLoader.java:360) ~[na:1.8.0_25] at java.lang.ClassLoader.loadClass(ClassLoader.java:424) ~[na:1.8.0_25] at java.lang.ClassLoader.loadClass(ClassLoader.java:357) ~[na:1.8.0_25] at java.lang.Class.forName0(Native Method) ~[na:1.8.0_25] at java.lang.Class.forName(Class.java:344) ~[na:1.8.0_25] at org.apache.spark.serializer.JavaDeserializationStream$$anon$1.resolveClass(JavaSerializer.scala:67) ~[spark-core_2.11-2.0.0.jar:2.0.0]
...
I am using spark-2.0.0-bin-hadoop2.7 distribution. And the dependencies listed in my SBT file are:
val scalatraVersion = "2.3.0"
val sparkVersion = "2.0.0"
val sprayVersion = "1.3.4"
libraryDependencies ++= Seq(
"org.scalatra" %% "scalatra" % scalatraVersion,
"org.scalatra" %% "scalatra-json" % scalatraVersion,
"org.scalatra" %% "scalatra-commands" % scalatraVersion,
"org.json4s" %% "json4s-jackson" % "3.2.9",
"ch.qos.logback" % "logback-classic" % "1.1.3" ,
"org.eclipse.jetty" % "jetty-webapp" % "9.2.10.v20150310",
"com.typesafe.akka" %% "akka-actor" % "2.3.4",
"org.apache.spark" %% "spark-core" % sparkVersion exclude("org.slf4j", "slf4j-log4j12"),
"org.apache.spark" %% "spark-sql" % sparkVersion,
"org.apache.spark" %% "spark-mllib" % sparkVersion,
"io.spray" %% "spray-can" % sprayVersion,
"io.spray" %% "spray-routing" % sprayVersion
)
Is this an issue with Scala 2.0.0, or I am missing some dependency ?
Regards,
Bhaskar
