: Yes, you can effectively chroot all the configs for a collection (to : support multiple collections in same ensemble) - see wiki: : http://wiki.apache.org/solr/SolrCloud#Zookeeper_chroot
I don't think chroot is suitable for what's being asked about here ... that would completely isolate two cloud clusters from eachother. i believe the intent of the question is asking about having a cloud cluster in which multiple collections exist, and some collections use differnet schema.xml files then other collections the short answer is: absolutely, each collecion can use completley differnet sets of configs (just like in non-cloud mode each core can use distinct configs) but to help make management easier when you have many collections re-using the same set of configs there is the concept of a "config set" ... you can push a set of configs into ZK with a specific "configName", nad then refer to that config set name when creating collections... https://wiki.apache.org/solr/SolrCloud#Getting_your_Configuration_Files_into_ZooKeeper http://wiki.apache.org/solr/SolrCloud#Managing_collections_via_the_Collections_API -Hoss
