All, I've thought I understood that Solr search requests are made to the Solr servers and NOT Zookeeper directly. (I.E. Zookeeper doesn't decide which Solr server responds to requests and requests are made directly to Solr)
My new place tells me they're sending requests to Zookeeper - and those are getting sent on to Solr by Zookeeper - -- this is news to me if it's true... Is there any documentation of exactly the role(s) played by Zookeeper in a SolrCloud setup?
