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