-------------------------------------

             Summary: Break up DDLSemanticAnalyzer - extract Table column analyzers
                 Key: HIVE-22644
                 URL: https://issues.apache.org/jira/browse/HIVE-22644
             Project: Hive
          Issue Type: Sub-task
            Reporter: Miklos Gergely
            Assignee: Miklos Gergely


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 #10: extract the table constraints related analyzers from DDLSemanticAnalyzer, and move
them under the new package.
