Wei Yan created YARN-1187:
-----------------------------

             Summary: Add discrete event-based simulation to yarn scheduler simulator
                 Key: YARN-1187
                 URL: https://issues.apache.org/jira/browse/YARN-1187
             Project: Hadoop YARN
          Issue Type: Improvement
            Reporter: Wei Yan
            Assignee: Wei Yan


Follow the discussion in YARN-1021.

Discrete event simulation decouples the running from any real-world clock. This allows users to step through the execution, set debug points, and definitely get a deterministic rexec.
