[jira] Created: (MAPREDUCE-1253) Making Mumak work with Capacity-Scheduler

Making Mumak work with Capacity-Scheduler
-----------------------------------------

                 Key: MAPREDUCE-1253
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-1253
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
          Components: contrib/mumak
    Affects Versions: 0.21.0, 0.22.0
            Reporter: Anirban Dasgupta
            Assignee: Anirban Dasgupta
            Priority: Minor


In order to make the capacity-scheduler work in the mumak simulation environment, we have to replace the job-initialization threads of the capacity scheduler with classes that perform event-based initialization. We propose to use aspectj to disable the threads  of the JobInitializationPoller class used by the Capacity Scheduler, and then perform the corresponding initialization tasks through a simulation job-initialization class that receives periodic wake-up calls from the simulator engine.
