[jira] [Created] (HIVE-4037) Merge a PTFOp for PTF invocation and a PTFOp for Windowing if possible

Harish Butani created HIVE-4037:
-----------------------------------

             Summary: Merge a PTFOp for PTF invocation and a PTFOp for Windowing if possible
                 Key: HIVE-4037
                 URL: https://issues.apache.org/jira/browse/HIVE-4037
             Project: Hive
          Issue Type: Bug
          Components: PTF-Windowing
            Reporter: Harish Butani
            Assignee: Prajakta Kalmegh


With patch for 3984 we removed the check during translation if windowing processing can be done at the end of a PTF chain.
Should do this check as an Optimization. If plan is:
PTFOp -> RS -> Extract -> PTFOp
and partitioning are compatible (ie same or only different in order) plan can be rewritten.
