             Summary: Break up DDLSemanticAnalyzer - extract Privilege related analyzers
                 Key: HIVE-22194
                 URL: https://issues.apache.org/jira/browse/HIVE-22194
             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 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 #2: extract all the functin related analyzers from DDLSemanticAnalyzer and FunctionSemanticAnalyzer and MacroSemanticAnalyzer, and move them under the new package.
