> Hive DDL has multiple problems:
>  * DDLTask is a huge class, needs to be cut to smaller pieces
>  * DDLSemanticAnalyzer is a huge class, needs to be cut to smaller pieces
>  * DDLWork has a bad structure by having a field for every possible DDL operation
>  * DDLDesc subclasses are put into one package which has an endless list of classes, should be separated by subjects
>  * Many DDLDesc subclasses are not immutable
