> In our environment, we use Kyuubi Spark AuthZ Plugin as a ranger plugin for
> spark, enable elasticsearch audit as well.After we submit spark task by
> spark-submit, the spark task would not exit even if the task is already
> finished.
> As we can know that spark driver main thread is finished, but there are some
> threads that were not daemon are still running, the JVM for spark driver
> cannot invoke shutdown hook, the JVM would exist all the way.
> In the jstack information, we get these threads is still in runnable status,
> as we expect, they are not daemon threads
> !image-2024-11-29-13-27-33-947.png!
> finally we find these threads were created by ElasticSearchAuditDestination
> Solution: set thread as daemon in RestClientBuilder, it is in
> ranger-plugins-audit
