https://github.com/apache/spark/pull/30227
> Support Column inputs in PySpark ordering functions (asc*, desc*)
> -----------------------------------------------------------------
>
> Key: SPARK-33257
> URL: https://issues.apache.org/jira/browse/SPARK-33257
> Project: Spark
> Issue Type: Bug
> Components: PySpark, SQL
> Affects Versions: 3.1.0
> Reporter: Maciej Szymkiewicz
> Priority: Major
>
> According to SPARK-26979, PySpark functions should support both {{Column}}
> and {{str}} arguments, when possible.
> However, the following ordering support only {{str}}
> - {{asc}}
> - {{desc}}
> - {{asc_nulls_first}}
> - {{asc_nulls_last}}
> - {{desc_nulls_first}}
> - {{desc_nulls_last}}
> support only {{str}}. This is because Scala side doesn't provide {{Column =>
> Column}} variants.
> To fix this, we do one of the following:
> - Call corresponding {{Column}} methods as
> [suggested|https://github.com/apache/spark/pull/30143#discussion_r512366978]
> by [~hyukjin.kwon]
> - Add missing signatures on Scala side.
