> DDLTask is a huge class, more than 5000 lines long. The related DDLWork is
> also a huge class, which has a field for each DDL operation it supports. The
> goal is to refactor these in order to have everything cut into more
> handleable classes under the package org.apache.hadoop.hive.ql.exec.ddl:
> * have a separate class for each operation
> * have a package for each operation group (database ddl, table ddl, etc), so
> the amount of classes under a package is more manageable
> * make all the requests (DDLDesc subclasses) immutable
> * DDLTask should be agnostic to the actual operations
> * right now let's ignore the issue of having some operations handled by
> DDLTask which are not actual DDL operations (lock, unlock, desc...)
> In the interim time when there are two DDLTask and DDLWork classes in the
> code base the new ones in the new package are called DDLTask2 and DDLWork2
> thus avoiding the usage of fully qualified class names where both the old and
> the new classes are in use.
> Step #10: extract the alter table operations that left from the old DDLTask,
> and move them under the new packages.
