- After more than a `week` of investigation and research, when we upgraded `Kubernetes client` from `6.x` to `7.0` and switched `default` HttpClient implementation from `OkHttp` to `Vert.x`, the issue of `Kubernetes Integration test` failure has been resolved. - The root cause is that some thread attributes `daemon` of `Vert.x` are set to `false`, so that after using `ProcessBuilder` to start the spark application on `K8S` (based on `spark-submit`), the `main thread` has already ended, but the above threads will not end, resulting in the overall `process` based on `spark-submit` not ending either. -- This is an automated message from the Apache Git Service.
