                 Key: SPARK-13742
                 URL: https://issues.apache.org/jira/browse/SPARK-13742

          Issue Type: Improvement
          Components: Spark Core

RandomSampler.sample currently accepts iterator as input and output another iterator. This makes it inappropriate to use in wholestage codegen of Sampler operator. We should add non-iterator interface to RandomSampler.
