             Summary: Get rid of magic constant __HIVE_DEFAULT_PARTITION__ in syntax
                 Key: HIVE-16638
                 URL: https://issues.apache.org/jira/browse/HIVE-16638
             Project: Hive
          Issue Type: Improvement
            Reporter: Daniel Dai


As per discussion in HIVE-16609, we'd like to get rid of magic constant __HIVE_DEFAULT_PARTITION__ in syntax. There are two use cases I currently realize:
1. alter table t drop partition(p='__HIVE_DEFAULT_PARTITION__');
2. select * from t where p='__HIVE_DEFAULT_PARTITION__';

Currently we switch p='__HIVE_DEFAULT_PARTITION__' to "p is null" internally for processing. It would be good if we can promote to the syntax level and get rid of p='__HIVE_DEFAULT_PARTITION__' completely.
