-----------------------------------
Summary: Add warning comment to SortExec.rowSorter
Key: SPARK-56250
URL: https://issues.apache.org/jira/browse/SPARK-56250
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 4.2.0
Reporter: L. C. Hsieh
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.
