Martin Tapp commented on SPARK-4940:
------------------------------------
I think the resource allocation strategy should be configurable. Round-robin
seems fit for many use cases, but others require other strategies such as
filling a node first. This strategy is useful when running many different
applications on a cluster.
> Support more evenly distributing cores for Mesos mode

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

> resources available on each slave.
