Simulate serialization when running local

[Ashic Mahtab]

Hi,Is there a way to simulate "networked" spark when running local (i.e. 
master=local[4])? Ideally, some setting that'll ensure any "Task not 
serializable" errors are caught during local testing? I seem to vaguely 
remember something, but am having trouble pinpointing it.
Cheers,Ashic.
