LuciferYang opened a new pull request, #13219: URL: https://github.com/apache/gravitino/pull/13219
### What changes were proposed in this pull request? `RemoveMetadataObject.equals` now casts to `RemoveMetadataObject`, compares both `metadataObject` and `locations`, and includes `locations` in `hashCode` to preserve the `equals`/`hashCode` contract. ### Why are the changes needed? After the `getClass()` guard the argument was cast to the sibling `RenameMetadataObject`, so comparing two `RemoveMetadataObject` instances (including `HashSet`/`contains`) always threw `ClassCastException`, and `locations` was ignored. Fix: #13216 ### Does this PR introduce _any_ user-facing change? No API change. Comparing two `RemoveMetadataObject` instances no longer throws `ClassCastException`, and `equals`/`hashCode` now take `locations` into account. ### How was this patch tested? Added `TestMetadataObjectChange`, which pins `equals`/`hashCode` for `RemoveMetadataObject` (comparing two instances, and `HashSet` membership); it fails on the pre-fix tree with `ClassCastException` and passes after the fix. -- This is an automated message from the Apache Git Service.
