Subject Re: issue about capacity scheduler
Date Thu, 05 Dec 2013 05:09:18 GMT

If both the jobs in the MR queue are from the same user, CapacityScheduler will only try to
run them one after another. If possible, run them as different users. At which point, you
will see sharing across jobs because they are from different users.

Thanks,
