Changing Schema.xml in SolrCloud setup

Question

how do i change the schema.xml for a collection in SolrCloud?

I have set up a zookeeper-ensemble on 3 nodes and i guess i could make the changes there, but don't know exactly.

Answer 1

As of Solr 5.x released, a Schema API was implemented to change the Schema more easily:

Answer 2

You can reload schema.xml for cores on SolrCloud by using zkCli.sh

Answer 3

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