> 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.
>  
> *Steps to reproduce*
> The following query will generate "{color:#6a8759}Error parsing partition 
> filter; lexer error" 
> [https://github.com/apache/hive/blob/master/standalone-metastore/metastore-server/src/main/java/org/apache/hadoop/hive/metastore/PartFilterExprUtil.java#L128]{color}
>  
> {color:#172b4d}When CBO is turned off (set hive.cbo.enable=false) we don't 
> see this error message.{color}
> {code:java}
> create table part_time(a int) partitioned by(date_c date);
> insert into part_time partition(date_c='2000-01-01') values (1);
> insert into part_time partition(date_c='2000-02-01') values (1);
> insert into part_time partition(date_c='2000-03-01') values (1); 
> select * from part_time where date_c = '2000-03-01';
> {code}

> *Performance Improvement [TODO]*
