> Issue Type: Bug
> Reporter: Jinfeng Ni
> Assignee: Julian Hyde
> Fix For: 1.4.0-incubating
>
>
> In PlannerImpl:ViewExpanderImpl, the code does not pass in
> ViewExpalnderImpl. That cause a view of another view will not be expanded
> properly.
> Also, ViewExpanderImpl's SqlToRelConverter does not have the same setting, or
> does not go throw the same transformation (flattenTypes, decorrelateQuery)
> step as the regular one in convert() method. That means some transformation
> might be missing to be applied to RelNode generated from a view.
