             Summary: MM: support (or disable) alter table concatenate
                 Key: HIVE-14899
                 URL: https://issues.apache.org/jira/browse/HIVE-14899
             Project: Hive
          Issue Type: Sub-task
            Reporter: Sergey Shelukhin


Doesn't make much sense for a table with lots of separate directories, at the first glance. However, it could concatenate files within separate directories if some insert produces a lot.
Merges between directories are also possible, as long as they take into account correctness of what is committed.
