> ExecutorClassLoader loads classes from SystemClassLoader
> --------------------------------------------------------

> Key: SPARK-19675
> URL: https://issues.apache.org/jira/browse/SPARK-19675
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Affects Versions: 2.1.0, 2.2.0
> Environment: sbt / Play Framework
> Reporter: Kohki Nishio
> Priority: Minor
>
> Spark Executor loads classes from SystemClassLoader which contains
> sbt-launch.jar and it contains Scala2.10 binary, however Spark itself is
> built on Scala2.11, thus it's throwing InvalidClassException
> java.io.InvalidClassException: scala.Option; local class incompatible: stream
> classdesc serialVersionUID = -114498752079829388, local class
> serialVersionUID = 5081326844987135632

> ExecutorClassLoader's desired class loder (parentLoader) actually contains
> the correct path (scala-library-2.11.8.jar) but it is not being used.
