If you click on the Cloudera Manager logo, do you see a cluster there?

If so, then I'm guessing that the wizard created the cluster and assigned all hosts to it, but didn't yet configure the services.

The easiest thing to do here is delete the cluster, then run the wizard again by clicking Add Cluster.

The scenario I described would happen if the wizard failed slightly earlier, after configuring CM agents but before creating the cluster.

Thanks,
