                 Key: TAJO-483
                 URL: https://issues.apache.org/jira/browse/TAJO-483
             Project: Tajo
          Issue Type: Improvement
    Affects Versions: 0.8-incubating
            Reporter: Jihoon Son

See the title.
In the current implementation, DirectedGraph provides getParent() which assumes that there
is only one parent. However, multiple parents should be supported in DirectedGraph.
