> HIVE-22941 was a quick workaround for empty files in case of external tables.
> An optimal solution would to completely prevent writing empty files just for
> having the table contents cleared on an empty INSERT OVERWRITE.
> There are other tickets about a similar topic, for example, if we need empty
> files at all: HIVE-22918, HIVE-22938
