Subject [jira] [Commented] (HIVE-4073) Make partition by optional in over clause
Date Tue, 26 Feb 2013 01:40:12 GMT


Ashutosh Chauhan commented on HIVE-4073:

sql spec allows empty specification in over clause. Currently, our parser fails to parse this
query. We have order-by optional but we don't need user to specify a partitioning spec. Infact
we should relax that requirement and if user chose not to specify the partitioning column
than partition by some constant value which achieves desired effect.
