> Right now, opportunistic container might not get allocated on rack local node
> even if it's available.
> Nodes are right now blacklisted if any container except node local container
> is allocated on that node. In case, if previously container was allocated on
> that node, that node wouldn't be even considered even if there is an ask for
> node local request.
