Hey,
I have a Spark Streaming application processing some events.
Sometimes, I want to stop the application if a get a specific event. I collect
the executor's results in the driver and based on those results, I kill the
StreamingContext using StreamingContext.stop(stopSparkContext=true).
When I do that, I can see in the logs that the app is shutting down, closing
receivers etc.
But when I go to the master's web UI I can still see the app under "Running
Applications". But if I click it, it says the endpoint doesn't exist.
When I check the open processes on the machine, I can see that the job's
process is still running.
Am I closing the application wrong?
Those are the logs once I call the stop() method:

timeoutMillis = 9223372036854775807 ms.
