URL: https://github.com/apache/spark/pull/39475#issuecomment-1381397038
@cloud-fan @ulysses-you I can confirm with #39468, the plan for the [example](https://github.com/apache/spark/pull/38356#issue-1419783566) now looks like
```
WriteFiles
+- *(1) Project [id#30, sort_col#31, empty2null(p#32) AS p#39]
+- *(1) Sort [p#32 ASC NULLS FIRST, sort_col#31 ASC NULLS FIRST], false, 0
+- ShuffleQueryStage 0
+- Exchange SinglePartition, REPARTITION_BY_NUM, [plan_id=68]
+- LocalTableScan [id#30, sort_col#31, p#32]
```
@ulysses-you can you please rebase with master or merge master into this branch
@cloud-fan can this go ahead then?
