-----------------------------------
Labels: pull-request-available (was: )
> Use explicit .apply instead of a case class companion as a function
> -------------------------------------------------------------------
>
> Key: SPARK-58043
> URL: https://issues.apache.org/jira/browse/SPARK-58043
> Project: Spark
> Issue Type: Sub-task
> Components: SQL
> Affects Versions: 4.3.0
> Reporter: Fangchen Li
> Priority: Major
> Labels: pull-request-available
>
> In Scala 2, a case class's companion object extends FunctionN, so the bare
> companion can be passed where a function is expected (xs.map(Foo),
> reduceLeft(And)). Scala 3 removed this, so such call sites fail to compile.
> Replacing Foo with Foo.apply (the method that FunctionN forwarded to) is
> byte-identical in Scala 2.13 and compiles on both versions. Affects 190 call
> sites across catalyst/sql-core/hive/sql-api.
