I have not exactly tested this but I dont think it will fail. A cleaned up
RDD should, for all purposes, same as a RDD that has never been submitted as
part of a job, so never computed. So it will just be recomputed from scratch.
Nonetheless, I agree, that cleanup should be exposed only with the propers
semantics and safeguards (throw exception if reused after explicit cleanup). So
for now we will not expose it. I have removed it and will updated the PR soon.
