Harish Butani commented on HIVE-3984:
-------------------------------------
Patch is attached.
- Spec and Def classes are redesigned.
- Phase1 and genPlan redone. Windowing & PTF translation are clearly separated.
- there is no more a dependency on antlr during runtime
Couple of issues remaining, will create Jiras for these:
- Need to do Column pruning for PTF Op for Windowing. (original test6 is
failing; will add it back once this is done)
- runtime has dependency on FuncRegistry; dependency has been removed for PTFs,
there is still a dependency for UDAFs.
> Maintain a clear separation between Windowing & PTF at the specification
> level.

> - refactor translation: both Phase 1 & GenPlan phases
