Hi all, looks we dropped 2.10 now - SPARK-19810. Would this JIRA be resolvable?

So the problem is somewhere along the caller list :) There might be a
workaround for 2.10 if you find the exact method that has different results.

For Scala 2.10, {{tpe}} is {{Tuple3}}. For Scala 2.11, it is {{(T1, T2, T3)}}.
Oh, seems Scala 2.10 somehow drops the type arguments.
btw, I am using scala 2.10.4 and scala 2.11.4.

No, it seems strange. I suggest you print out the `tpe` when it arrives in this
method and see if it's the same in 2.10 and 2.11. The error may happen earlier,
but it blows up here.

Yea, seems scala 2.11 is fine (I also tested this test in the branch 1.6 with
scala 2.11).
In ScalaReflection.scala, the following code has different behaviors when
running in scala 2.11
{code}
def getConstructorParameters(tpe: Type): Seq[(String, Type)] = {
val formalTypeArgs = tpe.typeSymbol.asClass.typeParams
val TypeRef(_, _, actualTypeArgs) = tpe
{code}
In scala 2.11, when {{tpe}} is {{(T1, T2, T3)}}, formalTypeArgs is {{List(type
T1, type T2, type T3)}} and actualTypeArgs is {{List(T1, T2, T3)}}. However, in
scala 2.10, formalTypeArgs is still {{List(type T1, type T2, type T3)}}, but
actualTypeArgs is {{List()}}.
[~dragos] Do you know any known issue with Scala 2.10 that may cause
{{TypeRef.unapply}} returns an empty list for type args when the type is a
{{Tuple3}} (or any Tuple)?

[jira] [Commented] (SPARK-17109) When we serialize UserDefinedGenerator to json, scala reflection throws an error
[

Yin Huai commented on SPARK-17109:
--
The definition of {{UserDefinedGenerator}} is
{code}
case class UserDefinedGenerator(
elementTypes: Seq[(DataType, Boolean, String)],
function: Row => TraversableOnce[InternalRow],
children: Seq[Expression])
{code}
Seems `elementTypes` causes this problem.
Seems scala 2.11 fixes this issue?
