Andrea Ferretti created SPARK-2330:
--------------------------------------

             Summary: Spark shell has weird scala semantics
                 Key: SPARK-2330
                 URL: https://issues.apache.org/jira/browse/SPARK-2330
             Project: Spark
          Issue Type: Bug
          Components: Spark Core
    Affects Versions: 1.0.0, 0.9.1
         Environment: Ubuntu 14.04 with spark-x.x.x-bin-hadoop2
            Reporter: Andrea Ferretti


Normal scala expressions are interpreted in a strange way in the spark shell. For instance

case class Foo(x: Int)
def print(f: Foo) = f.x
val f = Foo(3)
print(f)
<console>:24: error: type mismatch;
 found   : Foo
 required: Foo

For another example

trait Currency
case object EUR extends Currency
case object USD extends Currency

def nextCurrency: Currency = nextInt(2) match {
  case 0 => EUR
  case _ => USD
}

<console>:22: error: type mismatch;
 found   : EUR.type
 required: Currency
         case 0 => EUR

<console>:24: error: type mismatch;
 found   : USD.type
 required: Currency
         case _ => USD
