xasecure.audit.destination.elasticsearch true xasecure.audit.destination.elasticsearch.urls 1.1.1.x xasecure.audit.destination.elasticsearch.port 12345 xasecure.audit.destination.elasticsearch.protocol http xasecure.audit.destination.elasticsearch.user elastic xasecure.audit.destination.elasticsearch.password hhhdasd xasecure.audit.destination.elasticsearch.index ranger xasecure.audit.destination.elasticsearch.bootstrap.enabled true This is the configuration file ranger admin site. xml in my ranger.
