-------------------------------------
Assignee: Ruifeng Zheng
> Handle infinite relativeError in approxQuantile
> -----------------------------------------------
>
> Key: SPARK-58916
> URL: https://issues.apache.org/jira/browse/SPARK-58916
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 5.0.0
> Reporter: Ruifeng Zheng
> Assignee: Ruifeng Zheng
> Priority: Major
> Labels: pull-request-available
>
> DataFrameStatFunctions.approxQuantile derives approx_percentile accuracy from
> relativeError. Double.PositiveInfinity passes the existing non-negative
> relative-error validation, but ceil(1.0 / relativeError) produces accuracy 0,
> which approx_percentile rejects. Clamp the derived accuracy to at least 1.
