So, if I create (or edit) the correct entries in ZK, Solr should just pick
that up and behave accordingly?  I thought I had to do this through the
Solr API.  I think I'll experiment some more with this.

The shard information is gone from zookeeper (I guess that's what you mean
by ZK node?), and I can't specify hash ranges through the ADDREPLICA
command.

I'm not really interested in the data, since all data in the collection has
a TTL of 30 minutes.

I ended up re-creating the collection even though it gave me a couple of
minutes downtime.  If this happens again, it would be awesome if I could
 manually create the shards with the specified hash ranges.
