>
> We need to handle cases like ALTER TABLE ... CONCATENATE that also change the
> files on disk, and potentially treat them similar to INSERT OVERWRITE, as it
> does something equivalent to a compaction.
> Note that a ConditionalTask might also be fired at the end of inserts at the
> end of a tez task (or other exec engine) if appropriate HiveConf settings are
> set, to automatically do this operation - these also need to be taken care of
> for replication.
