Subject Re: Persist and unpersist

Oh, I see. Another idea would be to provide something like sc.prune(a,
b, c) that
traverses the dependency graph of RDDs a, b, c and unpersists any cached
RDDs not referenced by any other RDD. In this case you could store the
return value of blowUp and call prune on it after line 9.
