> Slider required to know about cluster nodes details for providing support for
> affinity/anti-affinity on containers.
> Current behavior : During life span of application , updatedNodes are sent in
> allocate request only if there are any change like added/removed/'state
> change' in the nodes. Otherwise cluster nodes not updated to AM.
> One of the approach thought by [[email protected]] is while AM registration
> let response hold the cluster nodes report
