rameshreddy-adutla opened a new pull request, #10215: URL: https://github.com/apache/gravitino/pull/10215
### What changes were proposed in this pull request? Add namespace validation in `TopicMetaService`'s private methods that directly index into namespace levels, preventing `ArrayIndexOutOfBoundsException` on malformed input. ### Why are the changes needed? `TopicMetaService#getTopicPOByFullQualifiedName` and `listTopicPOsByFullQualifiedName` assume the topic namespace always has 3 levels and directly access `namespaceLevels[0..2]`. For malformed input (fewer levels), this throws an uninformative `ArrayIndexOutOfBoundsException`. ### Does this PR introduce _any_ user-facing change? No. Internal defensive validation — the external API is unchanged. Malformed identifiers now produce a clear `NoSuchEntityException` instead of `ArrayIndexOutOfBoundsException`. ### How was this patch tested? Added unit test `testGetTopicByFullQualifiedNameMalformedNamespaceThrowsNoSuchEntityException` (as suggested in #10133) that: 1. Uses reflection to call the private `getTopicPOByFullQualifiedName` method 2. Passes a `NameIdentifier` with only 2-level namespace (missing schema) 3. Asserts `NoSuchEntityException` is thrown (wrapped in `InvocationTargetException`) Closes #10133 -- This is an automated message from the Apache Git Service.
