> The issue happens on cloud which provides virtual cores with software like Xen underneath. In effect if CPU intensive operators land up on same node we have a resource bottleneck,
> Need to create an attribute that does the following
> - Operators A & B should not be on same node
> - Stram should use this attribute to try to get containers on different node
> It is understood that the user is making an explicit choice to use NIC instead of stream local optimization
