Sahil Takiar commented on HIVE-18533:
-------------------------------------
I think {{Future}} is a better abstraction than a {{Thread}} in this scenario.
A {{Future}} provides a way to monitor an async operation, as well as get any
errors or results from the async computation. {{launchDriver}} is basically an
async operation, it launches the Spark app and then exits.
> Add option to use InProcessLauncher to submit spark jobs

> HoS session + debuggability (no need launch a separate process to run a Spark
> app).
