Description

Consider the following Spark REPL session:

scala> def showInt(implicit x: Int) = println(x)
showInt: (implicit x: Int)Unit

scala> object IntHolder { implicit val myInt = 5 }
defined module IntHolder

scala> import IntHolder.myInt
import IntHolder.myInt

scala> showInt
5

scala> class A; showInt
<console>:11: error: could not find implicit value for parameter x: Int
        showInt
        ^

This was most likely caused by the fix to SPARK-2632
