--------------------------------
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.
