Ted,
spark-catalyst_2.11-1.2.1.jar is present in the class path. BTW, I am running
the code locally in eclipse workspace.
Here’s complete exception stack trace -
Exception in thread "main" scala.ScalaReflectionException: class
org.apache.spark.sql.catalyst.ScalaReflection in JavaMirror with primordial
classloader with boot classpath
