    I think this makes more sense, although I think it might even be a smaller 
change and more widely applicable if it were an `InputFormat` decorator as 
@sryza mentioned. I don't know if for some reason that becomes hard to make 
work. A whole new RDD and a 'reliable' method (is the current method 
unreliable?) still seems like a lot of weight, to me, to deal with user-space 
problems, and ones that seem straightforward to solve directly (i.e. taste and 
delete bad files if you expect bad zip files). Transient failures can be helped 
by the internal retry logic but if the upstream data is just unreadable, how 
far do you go to make sense out of it?
