Weichen Xu commented on SPARK-22126:
------------------------------------
[~bago.amirbekian] Small correction: the callable definition can be
{code}
trait Callable[M] {
def call(): Map[Int, M]
}
{code}
so "fitMultiple" return type can still be `Array[Callable[M]`, I think we do
not need to make the generic type to be too complicated.
