Guangyuan Feng created KYLIN-5574:
-------------------------------------
Summary: Build model failed if any of the source table schema had
been changed, saying deleted unrelated columns.
Key: KYLIN-5574
URL: https://issues.apache.org/jira/browse/KYLIN-5574
Project: Kylin
Issue Type: Bug
Components: Modeling
Affects Versions: 5.0-alpha
Reporter: Guangyuan Feng
Fix For: 5.0-alpha
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.
