             Summary: deprecate unix_timestamp(void) and make it deterministic
                 Key: HIVE-10728
                 URL: https://issues.apache.org/jira/browse/HIVE-10728
             Project: Hive
          Issue Type: Bug
            Reporter: Sergey Shelukhin
            Assignee: Sergey Shelukhin


We have a proper current_timestamp function that is not evaluated at runtime.
Behavior of unix_timestamp(void) is both surprising, and is preventing some 
optimizations on the other overload since the function becomes 
non-deterministic.
