This is a review request for a port of the Fair Scheduler to MR2
someone familiar with the MR2 scheduling code would take a look at
This patch brings most of the Fair Scheduler features from MR1, with a
few exceptions (Web UI, Load Balancer) which I've deferred to future
commits. The patch is already somewhat large as-is.
I'm happy to take care of follow-up maintenance on the scheduler once
committed, in addition to the aforementioned future patches.
