Zhenhua Wang updated SPARK-22179: --------------------------------- Description: percentile_approx should choose the first element if it already reaches the percentage. For example, given input data 1 to 10, if a user queries 10% (or even less) percentile, it should return 1 (instead of 2), because the first value 1 already reaches 10%. Currently it returns a wrong answer: 2. was: percentile_approx should choose the first element if it already reaches the percentage.
