> After Insert overwrite into a non-empty partition/table with empty datasets,
> the subsequent query results are incorrect
> For example, current dataset of partition dt=2021-07-17 is
> ||id||name||dt||
> |1|'a'|'2021-07-17'|
>
> Using the following SQL to overwrite partition dt=2021-07-17
> {code:java}
> insert overwrite table targetT partition(dt='2021-07-17') select id, name,
> price from sourceT where dt=2021-07-17 and product='test'
> {code}
> If the input dataset is empty. We expect after insert overwrite, the
> partition of dt=2021-07-17 is empty.
> However, the query result is still the old data.
