----------------------------------

             Summary: All column resolving should be as fully qualified names.
                 Key: TAJO-1355
                 URL: https://issues.apache.org/jira/browse/TAJO-1355
             Project: Tajo
          Issue Type: Improvement
          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.
