Volodymyr Vysotskyi commented on CALCITE-2087:
----------------------------------------------
We had this method in our Drill-Calcite, so I created pull request
https://github.com/apache/calcite/pull/581 with a cherry-pick of commit, where
it was added. Could someone please take a look?
> Add new method to ViewExpander interface to allow passing SchemaPlus

> Currently, {{ViewExpander}} interface contains single method
> {{expandView(RelDataType rowType, String queryString, List<String>
> schemaPath, List<String> viewPath)}} which allows creating a {{RelNode}}
> instance that corresponds to the desired view.
> Drill supports impersonation for views and it is implemented in such a way,
> that its configs such as username, etc are stored in {{SchemaPlus}} instance.
> So currently it is not possible to pass these configs into this method to
> create {{CatalogReader}} and allow impersonation work.
