Hi,

If I issue either a core UNLOAD command, or a collection DELETEREPLICA
command,  (which both seem pretty much equivalent) it works but if there are
no other replicas for the shard, then the metadata for the shard is
completely gone in clusterstate.json!  That's pretty disconcerting because
you're basically hosed.  Of course, why would I even want to do that?  Well
I'm experimenting with ways to restore a backed-up replica to replace
existing data for the shard.

If this is unexpected behavior then I'll file a bug.

~ David
