[jira] [Created] (TAJO-419) Add missing visitor methods of AlgebraVisitor and BaseAlgebraVisitor

Hyunsik Choi created TAJO-419:
---------------------------------

             Summary: Add missing visitor methods of AlgebraVisitor and BaseAlgebraVisitor
                 Key: TAJO-419
                 URL: https://issues.apache.org/jira/browse/TAJO-419
             Project: Tajo
          Issue Type: Improvement
          Components: parser, planner/optimizer
            Reporter: Hyunsik Choi
            Assignee: Hyunsik Choi
             Fix For: 0.8-incubating


This patch primarily adds all missing operator types' visitor methods of AlgebraVisitor and implements concrete methods in BaseAlgebraVisitor. Currently, BaseAlgebraVisitor may cause incorrect PlanningException because BaseAlgebraVisitor does not handle all operator types. This patch eliminates this potential bug.

In addition, this patch contains two refactors in order to eliminate duplicate names:
 * Rename tajo.algebra.DataType to DataTypeExpr
 * Rename tajo.algebra.Target to TargetExpr
