> 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.
