Timothy Chen commented on SPARK-4940:
-------------------------------------
So I assume you're specifiying coarse grain mode right? And how are streaming
consumers launched?
I know that on the scheduler side it is launching spark executors/drivers, and
we simply launch one spark executor per slave that is running multiple spark
tasks.
My assumption was that it was the number of resources allocated that is
disproportional to each slave's executor.

> Currently in Coarse grain mode the spark scheduler simply takes all the

> resources available on each slave.
