One more question, in https://slider.incubator.apache.org/docs/configuration/resources.html#placement it says that "Once YARN adds support for this, Slider will support it." and https://issues.apache.org/jira/browse/YARN-1042 for "add ability to specify affinity/anti-affinity in container requests" is still unresolved. However in I see ANTI_AFFINITY_REQUIRED in https://github.com/apache/incubator-slider/blob/develop/slider-core/src/main/java/org/apache/slider/providers/PlacementPolicy.java#L57 and other places of the code. Is anti affinity implemented in slider before YARN-1042, by other means independent from that YARN feature? Is there a minimal version of YARN required to use anti affinity in Slider?
