László Bodor updated HIVE-22949:
--------------------------------
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
> Handle empty insert overwrites without inserting an empty file in case of
> acid/mm tables
