How to change schema.xml file for collection in SolrCloud?
I created a zookeeper ensemble on 3 nodes, and I think I could make changes there, but I donβt know for sure.
You can reload schema.xml for kernels on SolrCloud using zkCli.sh
More details in the Stackoverflow link: Restarting the zoo keeper solr conf (schema.xml)
With the release of Solr 5.x, the Schema API was implemented to more easily modify the schema:

The easiest way is to use 1 node as a bootloader, you can add bootstrap_configdir pointing to your configuration directory. Restarting the service will load the configuration files. Another option is to use ZkCli - here you can find usage examples: http://wiki.apache.org/solr/SolrCloud
