Siddharth Seth updated MAPREDUCE-4335:
--------------------------------------
Attachment: MR4335_2.txt
Updates unit-tests to work with the capacity-scheduler.
Some tests continue to use the FifoScheduler - specifically ones testing the
FifoScheduler. DistributedShell will need to be fixed to work with the CS -
creating a jira for this.
> Change the default scheduler to the CapacityScheduler

> 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.
