Subject [GitHub] spark pull request: [SPARK-13742][Core] Add non-iterator interface...

    Do we generate more random numbers than iterator call? I think it should be the same.
Besides, the non-iterator api should only be used in Sampler codegen #11517. It is expensive
to create a new iterator from values passed from Sampler node's child operator.
