When Solr loses it's connection to ZooKeeper, updates will start being
rejected. Read requests will continue as normal. This is regardless of how
long ZooKeeper is down.

I have to imagine I'm quibbling with the original assertion that Solr 4.x is
architected with a dependency on Zookeeper when I say the following:
Solr 4.x is not architected with a dependency on Zookeeper. SolrCloud,
however, is. As such, if a line of reasoning drives greater concern about
Hi,
Solr 4.x is architected with a dependency on Zookeeper, and Zookeeper is

In case all your Zk nodes go down, the querying would continue to work fine (as
far as no nodes fail) but you'd not be able to add docs.
