diqiu50 opened a new pull request, #10742: URL: https://github.com/apache/gravitino/pull/10742
### What changes were proposed in this pull request? Fix the `file:` scheme handler in `FetchFileUtils` to synchronize symlink creation and avoid concurrent races. Replace the non-atomic `exists() + delete()` in `KerberosClient` with `Files.deleteIfExists()`. Remove the unused duplicate `FetchFileUtils` in `catalog-hive` and add comprehensive tests in `hive-metastore-common`. ### Why are the changes needed? `Files.createSymbolicLink()` throws `FileAlreadyExistsException` when multiple threads concurrently fetch the same keytab path, such as when the search event listener triggers cascade sync after catalog creation. Fix: #10741 ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? - added unit coverage in `TestFetchFileUtils` including concurrent, idempotent, and target-replacement scenarios -- This is an automated message from the Apache Git Service.
