Hyunsik Choi commented on TAJO-1355:
------------------------------------
That may be one solution for this issue. Actually, LogicalPlanPreProcessor
partially replaces names with fully qualified names. But, it requires more
effort to replace fully them into fully qualified names.
> All column resolving should be as fully qualified names.

> Components: planner/optimizer
> Reporter: Hyunsik Choi
>
> Currently, schemas used in a logical plan includes fully qualified names and
> simple name without qualified names. It makes many parts complicated
> unnecessarily.
> For example, Schema class can be simplified if it maintains only qualified
> names. Binding correct columns in FieldEval can be simplified if we do it.
> Also, many query optimization code would be simple.
