I have a Ambari server installed HDP node that is only running zookeeper, HDFS, Yarn, and MapReduce2. I added the HDF Management Pack for 188.8.131.52 and wanted to install Kafka and Schema Registry. I realize kafka is already accessible with HDP, but I wanted to add the schema registry. When I went to add the kafka and schema registry services, I do not see schema registry as an available service. Ni-Fi, Ni-Fi registry and other HDF services are available, but not SAM or Schema Registry. Does anyone know why this would be?
