Review request for hive and Zoltan Haindrich.
Bugs: HIVE-21635
https://issues.apache.org/jira/browse/HIVE-21635
Repository: hive-git
Description
-------
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 #6: extract all the workload management related operations from the old
DDLTask, and move them under the new package.
