I checked the DAGScheduler code, L793, I think it's pretty straightforward
to move that functionality to here, as you will have an unified implementation
of SerializerAndRunner for all scheduler
backend....https://github.com/apache/spark/blob/master/core/src/main/scala/org/apache/spark/scheduler/DAGScheduler.scala#L770,
that line is actually just for checking if the task is serializable......
