> 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.
