[Bug]: create an unused .keep file in mixed_hive format table

[nicochen]

What happened?

It creates millions of '.keep' small files in my case and there is no mechanism to clean it up. It seems like '.keep' file is created and never been used. Perhaps it should not been created or implement an orphan clean logic to clean it up.

yes, as discussed offline, we can move the condition of whether the hive data changes forward and apply it to whether we need to create a catalogue or not
