          Components: Hive
            Reporter: Miklos Gergely
            Assignee: Miklos Gergely


Hive DDL has multiple problems:
 * DDLTask is a huge class, needs to be cut to smaller piecese
 * 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
