Rui Li commented on HIVE-18533:
-------------------------------

Thanks for the update [~stakiar]. There's some issue with 
TestSparkLauncherSparkClient. I think we can't assert the Future is done after 
we issue the state change -- there can be a race condition and it's not against 
the Future contracts. We can remove those assertions, or we can assert 
Future::get should return in some reasonable amount of time.

> Add option to use InProcessLauncher to submit spark jobs

> I think this will help with reducing the amount of time it takes to open a 
> HoS session + debuggability (no need launch a separate process to run a Spark 
> app).
