In Hive , __HIVE_DEFAULT_PARTITION__ is a special value used internally to represent:  NULL or EMPTY STRINGS in partition column values . Since it's just a string literal in the metadata , you can access it just like any other string in a query.  Example :  SELECT * FROM your_table WHERE data_dt = '__HIVE_DEFAULT_PARTITION__'; We cannot do WHERE data_dt IS NULL — because NULLs are replaced with __HIVE_DEFAULT_PARTITION__ before being written If you do WHERE length(data_dt) = 26 — it won’t match anything, because partition columns behave differently.  ...
