> Hit NPE when accessing api/vi/clusters/c1/hosts/c6403.ambari.apache.org.
> The repro steps are not simple as I was trying to close the browser during Add Host Wizard progress and then trying to delete the host to start the wizard again.
> In any case, we can add some null checks to avoid the NPE.
