Hey everybody, Just a heads up that currently Spark 2.0.1 has a compile dependency on Scalatest 2.2.6. It comes from spark-core's dependency on spark-launcher, which has a transitive dependency on spark-tags, which has a compile dependency on Scalatest.
This makes it impossible to use any other version of Scalatest for testing your app if you declare a dependency on any Spark 2.0.1 module; you'll get a bunch of runtime errors during testing (unless you figure out the reason like I did and explicitly exclude Scalatest from the spark dependency). I think that dependency should probably be moved to a test dependency instead. Thanks, Jeremy
