Description
When debugging Spark applications or deployments, it is often useful to inspect the Web UI of the driver application. Especially when the application is running remotely and facilities such as the history server aren't available, it can be limiting and frustrating that the UI stops when the application finishes. Developers sometimes add sleep statements to the end of their programs to allow to this, but this requires rebuilding an application to run it again with a delay.
It is useful to have a configuration property, such as spark.ui.stopDelay, that can be use with arbitrary applications to prevent the UI from stopping immediately.
