Key: HUDI-6828
URL: https://issues.apache.org/jira/browse/HUDI-6828
Project: Apache Hudi
Issue Type: Bug
Reporter: Jing Zhang
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 $target partition(dt='2021-07-17') select id, name,
price from sourceA 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.
