> 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.
