             Summary: Pushdown Date data type to metastore via direct sql / JDO
                 Key: HIVE-26778
                 URL: https://issues.apache.org/jira/browse/HIVE-26778
             Project: Hive
          Issue Type: Bug
            Reporter: Syed Shameerur Rahman
            Assignee: Syed Shameerur Rahman


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'
