Prasanth Jayachandran commented on HIVE-20540:
----------------------------------------------
Checking for row number set alone is sufficient right? Do we also need to check
for bucketNumSet? If not later flag can probably be removed.

> Followup to HIVE-20510 with remaining issues,

> 1. Avoid using Reflection.
> 2. In VectorizationContext, use correct place to setup the VectorExpression.
> It may be missed in certain cases.
> 3. In BucketNumExpression, make sure that a value is not overwritten before
> it is processed. Use a flag to achieve this.
