Issue Type: Bug (was: Improvement)
> Remove confusing defensive code in SortExec.rowSorter and add warning comment
> -----------------------------------------------------------------------------
>
> Key: SPARK-56250
> URL: https://issues.apache.org/jira/browse/SPARK-56250
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 4.2.0
> Reporter: L. C. Hsieh
> Assignee: L. C. Hsieh
> Priority: Major
> Labels: pull-request-available
>
> SPARK-52609 added some defensive code to SortExec. The defensive has some
> issues and was fixed by SPARK-56203.
> But actually the defensive code is not for Spark itself but to guard
> multithreading access to SortExec. The defensive code could easily confuse
> others. After rethinking about it, it might be better to revert it and add
> some warning comment.
