Description

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
