Stefan Savic created SPARK-55065:
------------------------------------
Summary: Avoid making two JDBC API calls
Key: SPARK-55065
URL: https://issues.apache.org/jira/browse/SPARK-55065
Project: Spark
Issue Type: Improvement
Components: Spark Core
Affects Versions: 4.1.1, 4.2.0
Reporter: Stefan Savic
Instead of explicitly calling tableExists in JDBCTableCatalog.loadTable(...),
this change now detects table existence by catching exceptions from
getQueryOutputSchema and checking it with dialect specific method
isObjectNotFoundException.
