yangwwei commented on issue #89: Core allocation/reservation logic renovation URL: https://github.com/apache/incubator-yunikorn-core/pull/89#issuecomment-585361646 The other thing is, when we score nodes while attempting to reserve resources, we need to make sure the candidate node satisfies the following condition - the node fits the predicates - the node has not been reserved - the node is scheduable right now the score is calculated based on resource only, that will lead the issue that reserve resources on a node that might not have a certain label to satisfy a node-selector, or against a affinity/anti-affinity constraint. which is an invalid reservation.
