> Currently, all execution nodes extend both from {{RelNode}} and {{ExecNode}}, and they share same input instances which is stored in the {{RelNode}} instance. {{ExecNode#getInputNodes}} just returns the casted {{RelNode}} inputs, code likes:
> {code:java}
> getInputs.map(_.asInstanceOf[ExecNode[_]])
> {code}
> This issue aim to let {{ExecNode}} have its own input instances. It is prepared for the implementation separation between {{RelNode}} and {{ExecNode}}.
