--------------------------------------------
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'
