             Summary: Expose Merge-File task and Column-Truncate task from DDLTask
                 Key: HIVE-13629
                 URL: https://issues.apache.org/jira/browse/HIVE-13629
             Project: Hive
          Issue Type: Improvement
          Components: Hive
    Affects Versions: 2.0.0
            Reporter: zhihai xu
            Assignee: zhihai xu


DDLTask will create subtask in mergeFiles and truncateTable to support HiveOperation.TRUNCATETABLE, HiveOperation.ALTERTABLE_MERGEFILES and HiveOperation.ALTERPARTITION_MERGEFILES.
It will be better to expose the tasks which are created at function mergeFiles and truncateTable from class DDLTask to users.
