Can't you extend a class in place of object which can be generic ?
class GenericAccumulator[B] extends AccumulatorParam[Seq[B]] {
}

Just realized that, of course, objects can't be generic, but how do I
create a generic AccumulatorParam?

Hi,
I have a problem with using accumulators in Spark. As seen on the Spark
website, if you want custom accumulators you can simply extend (with an
object) the AccumulatorParam trait. The problem is that I need to make that
object generic, such as this:
object SeqAccumulatorParam[B] extends A
