When I kill an application on the Web UI (which I submit with standalone-client mode), it seems to be killed already; But when I use 'jps' command I can still see the application running background. This is my demo code to reappear this problem.
- If I kill the application on web ui when section 1 rdd.map process, it can be stopped clearly;
- If I kill the application on web ui when section 2 do something in the driver, and then it stll running background.
So, is it a bug of spark and how to solve it ?
