-----------------------------------------------------------
In our private branch, I fix this and potential non-daemon thread introduced by other third party lib by adding SparkUncaughtExceptionHandler to KubernetesClusterSchedulerBackend
. [~dongjoon]
Driver Pod doesn't exit because there is a uncaught exception, kubernetes-client failed to call close method , and non-daemon thread block shutdownhook to get executed. With SparkUncaughtExceptionHandler, we can catch user/spark uncaught exception and Call System.exit which triggers shutdownhook to make things better.
How about this solution?
