------------------------------------
Resolution: Won't Do
> Possible log spew on DEBUG level from objects.Node

> When a predicate fails for a given node, we print a message on DEBUG level.
> The problem is, we keep doing this in every scheduling cycle, flooding the
> logs:
> {noformat}
> 2024-04-17T21:32:19.446Z DEBUG core.scheduler.node objects/node.go:403
> running predicates failed {"allocationKey":
> "2be04314-bed0-4385-9ae7-50ed0ef9d9d5", "nodeID": "kwok-node-zzn7w",
> "allocateFlag": true, "error": "predicates were not running because pod or
> node was not found in cache"}
> 2024-04-17T21:33:24.417Z DEBUG core.scheduler.node objects/node.go:403
> running predicates failed {"allocationKey":
> "2be04314-bed0-4385-9ae7-50ed0ef9d9d5", "nodeID": "kwok-node-zzn7w",
> "allocateFlag": true, "error": "predicates were not running because pod or
> node was not found in cache"}
> 2024-04-17T21:33:24.417Z DEBUG core.scheduler.node objects/node.go:403
> running predicates failed {"allocationKey":

> "allocateFlag": true, "error": "predicates were not running because pod or
> node was not found in cache"}
> {noformat}
> Another problematic part is {{preAllocateCheck()}} we have an allocation ask
> with a zero resource:
> {noformat}
> unc (sn *Node) preAllocateCheck(res *resources.Resource, resKey string) bool {
> // cannot allocate zero or negative resource
> if !resources.StrictlyGreaterThanZero(res) {
> log.Log(log.SchedNode).Debug("pre alloc check: requested
> resource is zero",
> zap.String("nodeID", sn.NodeID)) <-- will be printed
> from every node
> return false
> }
> ...
> {noformat}
> We need to reduce the amount of output with RateLimitedLogger.
