> The original feature to push down date data type while doing partition pruning via direct sql / JDO was added as part of the jira : https://issues.apache.org/jira/browse/HIVE-5679
> Since the behavior of Hive has changed with CBO, Now when CBO is turned on, The date data types are not pushed down to metastore due to CBO adding extra keyword 'DATE' with the original filter since the filter parser is not handled to parse this extra keyword it fails and hence the date data type is not pushed down to the metastore.
> {code:java}
> select * from test_table where date_col = '2022-01-01';
> {code}
> When CBO is turned on, The filter predicate generated is date_col=DATE'2022-01-01'  which the filter parser fails to recognize.
