> Key: SPARK-27919
> URL: https://issues.apache.org/jira/browse/SPARK-27919
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.0.0
> Reporter: Ryan Blue

> Priority: Major
>
> When no default catalog is set, the session catalog (v1) is responsible for table identifiers with no catalog part. When CTAS creates a table with a v2 provider, a v2 catalog is required and the default catalog is used. But this may cause Spark to create a table in a catalog that it cannot use to look up the table.
> In this case, a v2 catalog that delegates to the session catalog should be used instead.
