Julian Hyde resolved CALCITE-1900.
----------------------------------
Resolution: Fixed
Fix Version/s: 1.14.0
Fixed in http://git-wip-us.apache.org/repos/asf/calcite/commit/0cbd2a18. If a
query {{select * from A}} uses view A that uses B that uses C that uses B, then
the error message will be "Cannot resolve 'A'; it references view "schema.B',
whose definition is cyclic".
> Improve error message for cyclic views

> Detect that a view is cyclic (defined in terms of itself, or a view that
> depends on it) and give a better error message. Currently we get a stack
> overflow:
