Adding a bit of clarification to above mentioned solution. Find "Ranger External URL" in the field  Ranger > Configs > Advanced > Ranger Settings. It will be something like "http://<ranger_admin_host>:6080" . Copy this URL and update the particular service to which Ranger plugin is enabled. For example : If its HDFS, HDFS > Configs > Advanced > Advanced ranger-hdfs-security > ranger.plugin.hdfs.policy.rest.url. Usually this field should be auto populated by Ranger External URL value. If its not, it will be like "{{policy_mgr_url}}". Update this field by adding "Ranger External URL". Restart Ranger service, ranger KMS service and all required services.  ... View more
