R J commented on ARROW-11432:
-----------------------------
I'm not sure there is an easy fix without making breaking changes to the public
API. When building a join schema, it checks if the join set is valid
(physical_plan::hash_utils::check_join_set_is_valid), which has a parent public
API call (physical_plan::hash_utils::check_join_is_valid). This join is unaware
of the registered name (CSV or parquet) as it is performed with arrow schemas
rather than DataFusion schemas.
