> DDLSemanticAnalyzer is a huge class, more than 4000 lines long. The goal is to refactor
it in order to have everything cut into more handleable classes under the packageĀ  org.apache.hadoop.hive.ql.exec.ddl:
>  * have a separate class for each analyzers
>  * have a package for each operation, containing an analyzer, a description, and an operation,
so the amount of classes under a package is more manageable
> Step #12: extract the table partition related analyzers from DDLSemanticAnalyzer, and
move them under the new package.
