This PR has been merged into Spark 2.4. You can now do

val profileDF = Seq(
  Some(1), Some(2), Some(3), Some(4),
  Some(5), Some(6), Some(7), None
).toDF("profileID")

val validUsers: Set[Any] = Set(6, 7.toShort, 8L, "3")

val result = profileDF.withColumn("isValid", $"profileID".isInCollection(validUsers))

result.show(10)
"""
+---------+-------+
|profileID|isValid|
+---------+-------+
|        1|  false|
|        2|  false|
|        3|   true|
|        4|  false|
|        5|  false|
|        6|   true|
|        7|   true|
|     null|   null|

Spark 1.4 or older:

val validValues = Set("A", "B", "C").map(lit(_))
data.filter($"myColumn".in(validValues.toSeq: _*))

Spark 1.5 or newer:

val validValues = Set("A", "B", "C")
data.filter($"myColumn".isin(validValues.toSeq: _*))
