Julien Champ commented on SPARK-19451:
--------------------------------------

Thanks [~uncleGen] for your answer.

I was tempted to try to fix it myself.. But not sure of possible side effects.
If I can help you in any way ( code / debug / tests ), feel free to ask.

P.S. : I think this affects all version of Spark with Window functions, but I have only tested
it on spark 1.6.1 and 2.0.2

> Hi there,
> there seems to be a major limitation in spark window functions and rangeBetween method.
> If I have the following code :
> {code:title=Exemple |borderStyle=solid}
>     val tw =  Window.orderBy("date")
>       .partitionBy("id")
>       .rangeBetween( from , 0)
> {code}
> Everything seems ok, while *from* value is not too large... Even if the rangeBetween()
method supports Long parameters.
> But.... If i set *-2160000000L* value to *from* it does not work !
> It is probably related to this part of code in the between() method, of the WindowSpec
class, called by rangeBetween()
> {code:title=between() method|borderStyle=solid}
>     val boundaryStart = start match {
>       case 0 => CurrentRow
>       case Long.MinValue => UnboundedPreceding
>       case x if x < 0 => ValuePreceding(-start.toInt)
>       case x if x > 0 => ValueFollowing(start.toInt)
>     }
> {code}
> ( look at this *.toInt* )
> Does anybody know it there's a way to solve / patch this behavior ?
> Any help will be appreciated
> Thx
