Description

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.
