Ryan Lo commented on YUNIKORN-910:
----------------------------------
I ran the "pod-anti-affinity-example.yaml" on a single node K8s cluster
(v.1.21.5), 1 pod was running correctly and the other was pending.
{code:bash}
ryan@ryan-minikube:~$ k get events -n yunikorn | grep -i with-pod-affinity-01
2m11s Normal Scheduling pod/with-pod-affinity-01
yunikorn/with-pod-affinity-01 is queued and waiting for allocation

Then, I ran the same example on my K8s cluster (v1.21.5) with two worker nodes,
and two pods were assigned to different nodes as we expected.
{code:bash}
