---------------------------------

             Summary: Add a validation phase before construct RelNode using TableAPI
                 Key: FLINK-3754
                 URL: https://issues.apache.org/jira/browse/FLINK-3754
             Project: Flink
          Issue Type: Improvement
          Components: Table API
    Affects Versions: 1.0.0
            Reporter: Yijie Shen
            Assignee: Yijie Shen


Unlike sql string's execution, which have a separate validation phase before RelNode construction, Table API lacks the counterparts and the validation is scattered in many places.

I suggest to add a single validation phase and detect problems as early as possible.
