> 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 package 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 #13: extract the table info and lock related analyzers from
> DDLSemanticAnalyzer, and move them under the new package.
