----------------------------------

             Summary: False negative in QueryTest.checkAnswer
                 Key: SPARK-10591
                 URL: https://issues.apache.org/jira/browse/SPARK-10591
             Project: Spark
          Issue Type: Bug
          Components: SQL, Tests
    Affects Versions: 1.5.0, 1.4.1, 1.3.1, 1.2.2, 1.1.1, 1.0.2
            Reporter: Cheng Lian


# For double and float, `NaN == NaN` is always `false`
# `checkAnswer` doesn't handle `Map` properly. For example:
  {noformat}
  scala> Map(1 -> 2, 2 -> 1).toString
  res0: String = Map(1 -> 2, 2 -> 1)

  scala> Map(2 -> 1, 1 -> 2).toString
  res1: String = Map(2 -> 1, 1 -> 2)
  {noformat}
  We can't rely on `toString` to compare `Map` instances.

Need to update `checkAnswer` to special case `NaN` and `Map`.
