--------------------------------

             Summary: Extend YARN to support distributed scheduling
                 Key: YARN-2877
                 URL: https://issues.apache.org/jira/browse/YARN-2877
             Project: Hadoop YARN
          Issue Type: New Feature
          Components: nodemanager, resourcemanager
            Reporter: Sriram Rao


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).
