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

             Summary: Change the default scheduler to the CapacityScheduler
                 Key: MAPREDUCE-4335
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-4335
             Project: Hadoop Map/Reduce
          Issue Type: Task
          Components: mrv2
    Affects Versions: 2.0.0-alpha
            Reporter: Siddharth Seth
            Assignee: Siddharth Seth


There's some bugs in the FifoScheduler atm - doesn't distribute tasks across nodes and some
headroom (available resource) issues.
That's not the best experience for users trying out the 2.0 branch. The CS with the default
configuration of a single queue behaves the same as the FifoScheduler and doesn't have these
issues.
