> 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.
