Alejandro Abdelnur commented on YARN-1042:
------------------------------------------

it seems much of this could be achieved via YARN-796

> container requests to the AM should be able to request anti-affinity to ensure that things
like Region Servers don't come up on the same failure zones. 
> Similarly, you may be able to want to specify affinity to same host or rack without specifying
which specific host/rack. Example: bringing up a small giraph cluster in a large YARN cluster
would benefit from having the processes in the same rack purely for bandwidth reasons.
