OPSAPS-68708: Schema Registry might fail to start if a load balancer address is specified in Ranger
Schema Registry does not start if the address specified in the Load Balancer Address Ranger property does not end with a trailing slash (/).
Set the value of the RANGER_REST_URL Schema Registry environment variable to an address that includes a trailing slash.
  1. In Cloudera Manager, select the Schema Registry service.
  2. Go to Configuration.
  3. Find the Schema Registry Server Environment Advanced Configuration Snippet (Safety Valve) property and add the following:
    Key: RANGER_REST_URL
Value: [***RANGER REST API URL***]
    Replace [***RANGER REST API URL***] with an address that can be used by Schema Registry to access Ranger. Ensure that the address ends with a trailing slash. For example: https://ranger-1.cloudera.com:6182/
  4. Restart the Schema Registry service.
