> Using IS NOT DISTINCT FROM as an equi condition in HashJoin produced incorrect results under the Enumerable convention. So in CALCITE-6904 , IS NOT DISTINCT FROM was treated as a non-equi condition. 
> This work will fix the incorrect execution behavior and support  IS NOT DISTINCT FROM as an equi condition of HashJoin.
