             Summary: Implement LogicalNode visitor designed for plan transformation
                 Key: TAJO-2137
                 URL: https://issues.apache.org/jira/browse/TAJO-2137
             Project: Tajo
          Issue Type: Sub-task
          Components: Planner/Optimizer
            Reporter: Hyunsik Choi


The current logical node visitor is not good for plan transformation. The main objective of this issue is to design and implement the visitor for plan transformation. In other words, each visit of the visitor should result in an immutable node.
