It looks like any changes to configuration files need to be partnered with a rolling restart of the cloud: http://wiki.apache.org/solr/SolrCloud#Example_C:_Two_shard_cluster_with_shard_replicas_and_zookeeper_ensemble
ZooKeeper Multiple Zookeeper servers running together for fault tolerance and high availability is called an ensemble. For production, it's recommended that you run an external zookeeper ensemble rather than having Solr run embedded servers. See the Apache ZooKeeper site for more information on downloading and running a zookeeper ensemble. More specifically, try Getting Started and ZooKeeper Admin. It's actually pretty simple to get going. You can stick to having Solr run ZooKeeper, but keep in mind that a ZooKeeper cluster is not easily changed dynamically. Until further support is added to ZooKeeper, changes are best done with rolling restarts. Handling this in a separate process from Solr will usually be preferable. -- View this message in context: http://lucene.472066.n3.nabble.com/Updating-configuration-files-when-using-Solr-Cloud-tp4029207p4029218.html Sent from the Solr - User mailing list archive at Nabble.com.
