> URL: https://issues.apache.org/jira/browse/TAJO-419
> Project: Tajo
> Issue Type: Improvement
> Components: parser, planner/optimizer
> Reporter: Hyunsik Choi

>
> 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
