Changing the replication factor for a Solr keyspace
Steps for changing the keyspace replication factor after the solrconfig.xml and schema.xml files are posted.
Assuming the solrconfig.xml and schema.xml files have already been posted using mykeyspace.mysolr in the URL, which creates a keyspace named mykeyspace that has a default replication factor of 1. You want three replicas of the keyspace in the cluster, so you need to update the Solr keyspace replication factor.
