Description

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.
