[jira] [Created] (HIVE-23868) Windowing function spec: support 0 preceeding/following

Jason Dere created HIVE-23868:
---------------------------------

             Summary: Windowing function spec: support 0 preceeding/following
                 Key: HIVE-23868
                 URL: https://issues.apache.org/jira/browse/HIVE-23868
             Project: Hive
          Issue Type: Bug
          Components: Query Planning
            Reporter: Jason Dere
            Assignee: Jason Dere


HIVE-12574 removed support for 0 PRECEDING/FOLLOWING in window function specifications. We can restore support for this by converting 0 PRECEDING/FOLLOWING to CURRENT ROW in the query plan, which should be the same.
