Joy-2000 opened a new pull request, #19432: URL: https://github.com/apache/hudi/pull/19432
### Describe the issue this Pull Request addresses `StreamWriteOperatorCoordinator.start()` initializes several fields that are required by later coordinator operations, such as `metaClient`, `writeClient`, `executor`, and related coordinator state. Previously, if startup failed, the coordinator called `context.failJob(throwable)`. This can trigger an in-graph global failover while keeping the same coordinator instance alive. In that path, Flink may restore the job without invoking `start()` again on the same coordinator instance. If the original startup failed before all fields were initialized, the restored coordinator can continue running with null fields and later fail with `NullPointerException`. ### Summary and Changelog This PR updates `StreamWriteOperatorCoordinator.start()` to rethrow startup failures as a `HoodieException`. Changes: - Replace `context.failJob(throwable)` in the `start()` failure path with `throw new HoodieException(...)`. ### Impact None ### Risk Level low ### Documentation Update none ### Contributor's checklist - [ ] Read through [contributor's guide](https://hudi.apache.org/contribute/how-to-contribute) - [ ] Enough context is provided in the sections above - [ ] Adequate tests were added if applicable -- This is an automated message from the Apache Git Service.
