Field Detail

STORE_BASE_URL

public static final boolean STORE_BASE_URL

Feature flag to enable storing the 'base_url' property; base_url will not be stored as of Solr 9.x. Installations that use an older (pre-8.8) SolrJ against a 8.8.0 or newer server will need to set this system property to true to avoid NPEs when reading cluster state from Zookeeper, see SOLR-15145.

propMap

protected final Map<String,Object> propMap

Constructor Detail
