Class SolrSchemaUpgrader

java.lang.Object

edu.ucsb.nceas.metacat.admin.upgrade.solr.SolrSchemaUpgrader

public class SolrSchemaUpgrader
extends Object

This class will overwrite the existing schema under the /solr-home/conf/schema.xml Here is the algorithm: 1. If the hash value of the existing schema.xml is a one in the list of released schema (this means the administrator didn't customize the schema ), we will overwrite the schema.xml and remove the solr-last-proccessed-date file. The removal of the solr-last-proccessed-date file will force the metacat-index to rebuild all solr index when the administrator restart the tomcat at next time. 2. If the hash value of the existing schema.xml isn't in the list, an exception will be throw.
