I think you identified the problem correctly, @amogh-jahagirdar. We have to take into account the read attributes when determining the nullability of `MergeRows` output. This matches [what](https://github.com/apache/spark/blob/7ab7509fa12418ff5f93782670b7e939c055703a/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/analysis/RewriteMergeIntoTable.scala#L186) we did in Spark. Just to be sure, can you set `spark.sql.planChangeLog.level` to info and execute the failing test to see what rule adds the default value behavior? -- This is an automated message from the Apache Git Service.
