## Proposed Fix
Planning to issue a PR with:
### Fix 1: Preserve `stageCreate` flag in IcebergTableOperationExecutor
**File:**
`core/src/main/java/org/apache/gravitino/catalog/lakehouse/iceberg/ops/IcebergTableOperationExecutor.java`
When the executor rebuilds a `CreateTableRequest` to override the owner, it
should now preserves the `stageCreate=true` flag:
```java
if (createTableRequest.stageCreate()) {
builder.stageCreate(); // Preserve staging flag
}
```
Fix 2: Custom staging implementation for JDBC catalogs
File: IcebergCatalogWrapper.java
Add stageTableCreateWithoutCommit() method that bypasses Iceberg's
CatalogHandlers.stageTableCreate() (which incorrectly calls createTransaction()
for JDBC catalogs). This custom implementation:
Computes table location without accessing the catalog (which would trigger a
commit)
Builds TableMetadata with proper defaults (Iceberg automatically adds
timestamps)
Returns staged metadata without catalog registration, allowing the 3-phase
migration protocol to work correctly
