### What problem does this PR solve? Concurrent first consumers of a catalog's Hadoop properties could observe the cache before its initialization completed. One thread could copy the `HashMap` while the initializer was still populating it, causing a `ConcurrentModificationException` during external table sink binding. ### What is changed? - Build the Hadoop property map locally and publish it through the volatile cache only after all entries and the filesystem cache key are ready. - Add a deterministic concurrency regression test that verifies readers cannot observe a partially initialized cache. ### Validation - `CatalogPropertyTest` - `PaimonWriteBindingTest` - `StoragePropertiesFsCacheFingerprintTest` - FE Checkstyle -- This is an automated message from the Apache Git Service.
