Resolution: Duplicate
> Add API to calculate the approximate quantiles for multiple columns
> -------------------------------------------------------------------
>
> Key: SPARK-14432
> URL: https://issues.apache.org/jira/browse/SPARK-14432
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Reporter: Liang-Chi Hsieh
> Assignee: Liang-Chi Hsieh
> Priority: Minor
>
> As we have the underlying implementation to calculate the approximate
> quantiles for multiple columns, I think we have no reason only providing API
> to calculate the approximate quantiles for just one column at a time. We
> should add API to do multiple columns too.
