Kent Yao ef4c298cc9 [SPARK-29405][SQL] Alter table / Insert statements should not change a table's ownership ... ### What changes were proposed in this pull request? In this change, we give preference to the original table's owner if it is not empty. ### Why are the changes needed? When executing 'insert into/overwrite ...' DML, or 'alter table set tblproperties ...' DDL, spark would change the ownership of the table the one who runs the spark application. ### Does this PR introduce any user-facing change? NO ### How was this patch tested? Compare with the behavior of Apache Hive Closes #26068 from yaooqinn/SPARK-29405.
