Description Seth Jennings 2019-04-12 18:12:35 UTC
After the cluster is up for just a short time the number of revisions of the kube-scheduler is very high.  After 20m, we are near revision 100.

Hi Seth,
after 28h, there's no a lot of revisions of cm as below, is this good enough for pushing the bug to VERIFIED?

[nathan@dhcp-140-199 0422]$ oc get cm
