Description
How Ambari determines service state (https://github.com/apache/ambari/blob/trunk/ambari-server/docs/api/v1/service-resources.md) is not clear. For example, is HDFS considered STARTED when the NameNode and all DataNodes are up? For alternative implementations of Ambari server, understanding how this is currently done would be helpful. Until then, making the state retuned by clusters/<cluster_name>/services/<service_name> optional would give other implementers more flexibility.
