> This looks like an infinite planning bug in Calcite.  To reproduce, copy the two referenced TPCH Parquet files from contrib/data/tpch-sample-data/parquet/ to dfs.tmp then run the following. Uncommenting the `magic_fix` column is just one of the changes that can be made to make the query planning succeed.
