Hive's + * {@code IcebergInputFormat} calls {@code scan.planTasks()} via + * {@code IcebergInputFormat#getSplits}, which reloads a live REST catalog table for {@code POST /plan} + * (pinned to the serialized compile-time snapshot).

I removed the old catalog-type gate, `propagateVendedCredentialsToJob` keeps its own vended check, and I added unit and IT coverage for both the positive and negative cases. -- This is an automated message from the Apache Git Service.
