----------------------------------
We need to distinguish the situations, some need to be changed to
`.toIndexedSeq`, some need to be changed to `ArraySeq.unsafeWrapArray`
> Fix `Passing an explicit array value to a Scala varargs method is deprecated`

> Key: SPARK-45687
> URL: https://issues.apache.org/jira/browse/SPARK-45687
> Project: Spark
> Issue Type: Sub-task
> Components: Spark Core, SQL
> Affects Versions: 4.0.0
> Reporter: Yang Jie
> Priority: Major
>
> Passing an explicit array value to a Scala varargs method is deprecated
> (since 2.13.0) and will result in a defensive copy; Use the more efficient
> non-copying ArraySeq.unsafeWrapArray or an explicit toIndexedSeq call
>
> {code:java}
