[jira] [Created] (TAJO-1882) Clean up GreedyHeuristicJoinOrderAlgorithm::getCost APIs

Hyunsik Choi created TAJO-1882:
----------------------------------

             Summary: Clean up GreedyHeuristicJoinOrderAlgorithm::getCost APIs
                 Key: TAJO-1882
                 URL: https://issues.apache.org/jira/browse/TAJO-1882
             Project: Tajo
          Issue Type: Improvement
            Reporter: Hyunsik Choi
            Priority: Trivial


See the title. The definition of {{GreedyHeuristicJoinOrderAlgorithm::getCost}} is somewhat ambiguous. In Java 8, it requires explicitly type casting. We can clean up its APIs by renaming them to be different.
