>
> It's found that a Spark application is leaked when user cancels query and
> closes the session while Hive is waiting for remote driver to connect back.
> This is found for asynchronous query execution, but seemingly equally
> applicable for synchronous submission when session is abruptly closed. The
> leaked Spark application that runs Spark driver connects back to Hive
> successfully and run for ever (until HS2 restarts), but receives no job
> submission because the session is already closed. Ideally, Hive should
> rejects the connection from the driver so the driver will exist.
