> When users try to connect to remote cluster from the cluster env where you enabled ViewFSOverloadScheme, it expects to have at least one mount link make fs init success. 
> Unfortunately you might not have configured any mount links with that remote cluster in your current env. You would have configured only with your local clusters mount points.
> In this case fs init will fail with no mount points configured the mount table if that remote cluster uri's authority.
> One idea is that, when there are no mount links configured, we should just consider that as default cluster, that can be achieved by considering it as fallback option automatically.
