I will follow your suggestion to fix it in #28833 , since this PR is a refator with new type `HiveVoidType`. Now we don't need it. This is an automated message from the Apache Git Service.

If we mix VOID and NULL, I am not sure it would be better than separation. ```scala def failVoidType(dt: DataType): Unit = { if (HiveVoidType.containsVoidType(dt)) { throw new AnalysisException( "Cannot create tables with Hive VOID type.") } } ``` This is an automated message from the Apache Git Service.
