I just looked at the possible solution to update broadcast var info upon
the stage finished (just attempted to implement this in a single commit so that
I can easily revert to shorten the RTT), the problem is, how to associate a
broadcast variable with the stage....I didn't find a very reasonable solution
on this, because for RDD, we need that information to create a stage object, so
everything works straightforwardly...for broadcast...I'm not sure if we can
really do that....maybe I missed something
@shivaram @rxin ?
