> This is an umbrella JIRA that proposes to extend YARN to support distributed scheduling.
 Briefly, some of the motivations for distributed scheduling are the following:
> 1. Improve cluster utilization by opportunistically executing tasks otherwise idle resources
on individual machines.
> 2. Reduce allocation latency.  Tasks where the scheduling time dominates (i.e., task
execution time is much less compared to the time required for obtaining a container from the
RM).
