             Summary: Add lower bound on sampling rate to guarantee sampling performance
                 Key: SPARK-2145
                 URL: https://issues.apache.org/jira/browse/SPARK-2145
             Project: Spark
          Issue Type: Improvement
            Reporter: Doris Xin
            Priority: Minor


For extremely small sampling rates p < 10^-10, we want to prevent resampling caused by the RNG not returning completely random numbers.
