> URL: https://issues.apache.org/jira/browse/KYLIN-5574
> Project: Kylin
> Issue Type: Bug
> Components: Modeling
> Affects Versions: 5.0-alpha
> Reporter: Guangyuan Feng
> Priority: Major
> Fix For: 5.0-beta
>
>
> *How the error occurred?*
> During building 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.
