https://github.com/apache/seatunnel/issues/10226 <!-- Thank you for contributing to SeaTunnel! Please make sure that your code changes are covered with tests. And in case of new features or big changes remember to adjust the documentation. Feel free to ping committers for the review! ## Contribution Checklist - Make sure that the pull request corresponds to a [GITHUB issue](https://github.com/apache/seatunnel/issues). - Name the pull request in the form "[Feature] [component] Title of the pull request", where *Feature* can be replaced by `Hotfix`, `Bug`, etc. - Minor fixes should be named following this pattern: `[hotfix] [docs] Fix typo in README.md doc`. --> ### Purpose of this pull request <!-- Describe the purpose of this pull request. For example: This pull request adds checkstyle plugin.--> This PR improves Hive connector metastore HA by: - Using RetryingMetaStoreClient (when available) for metastore retry/failover, with a safe fallback to HiveMetaStoreClient. - Supporting comma-separated metastore_uri (with whitespace trimming), so users can configure multiple HMS endpoints for automatic failover. - Fixing HiveServer2 JDBC URL derivation when metastore_uri contains multiple URIs (derive from the first URI only). ### Does this PR introduce _any_ user-facing change? Yes. metastore_uri now supports multiple HMS URIs separated by commas (whitespace is allowed), and the connector will fail over to the next available metastore if the first one is unreachable. <!-- Note that it means *any* user-facing change including all aspects such as the documentation fix. If yes, please clarify the previous behavior and the change this PR proposes - provide the console output, description and/or an example to show the behavior difference if possible. If possible, please also clarify if this is a user-facing change compared to the released SeaTunnel versions or within the unreleased branches such as dev. If no, write 'No'. If you are adding/modifying connector documents, please follow our new specifications: https://github.com/apache/seatunnel/issues/4544. --> ### How was this patch tested? <!-- If tests were added, say they were added here. Please make sure to add some test cases that check the changes thoroughly including negative and positive cases if possible. If it was tested in a way different from regular unit tests, please clarify how you tested step by step, ideally copy and paste-able, so that other reviewers can test and check, and descendants can verify in the future. If tests were not added, please describe why they were not added and/or why it was difficult to add. If you are adding E2E test cases, maybe refer to https://github.com/apache/seatunnel/blob/dev/seatunnel-e2e/seatunnel-connector-v2-e2e/connector-cdc-mysql-e2e/src/test/resources/mysqlcdc_to_mysql.conf, here is a good example. --> 1. Unit tests added: HiveMetaStoreCatalogMetastoreUrisTest.java 2. E2E tests added: HiveIT.java and configs: - fake_to_hive_metastore_uri_failover.conf - hive_to_assert_metastore_uri_failover.conf ### Check list * [ ] If any new Jar binary package adding in your PR, please add License Notice according [New License Guide](https://github.com/apache/seatunnel/blob/dev/docs/en/contribution/new-license.md) * [ ] If necessary, please update the documentation to describe the new feature. https://github.com/apache/seatunnel/tree/dev/docs * [ ] If necessary, please update `incompatible-changes.md` to describe the incompatibility caused by this PR. * [ ] If you are contributing the connector code, please check that the following files are updated: 1.
