Scott Blum updated SOLR-6629:
-----------------------------
Attachment: SOLR-6629.patch
Second pass, I think this is actually in a good state. We do need to chat
through the new handling of lazyCollections some more, but I thought I would
present to you a working version in code of what I was talking about.
We should also consider optimizing lazyCollectionState to do temporary caching
(cache for 2 seconds?) to avoid hitting ZK rapidly in succession.

> The main clusterstate.json is refreshed/used as a poor substitute for
> informing all nodes about new or deleted collections even when the collection
> being created or deleted has state format > 1. When we move away from state
> format 1 then we should do away with this workaround and start watching the
> /collections zk node on all nodes.
