> *How the error occurred?*
> During build a model, KE will construct a new SELECT sql from KE's table
> metadata, to read data from source tables. But if the user had deleted some
> unused columns from any source table, KE's metadata will be different with
> Hive's metastore, as a consequence, `SparkSession::sql` will throws
> validation exceptions because of the mismatched columns found in the SELECT
> sql.
> *How to solve it?*
> Using the intersection between KE's columns and Hive metastore's.
