Could you put this into `exceptions.scala` and document it?
> 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.
