             Summary: Referenced Kerberos identity definitions should be created and distributed only if the referenced service or component is installed
                 Key: AMBARI-20540
                 URL: https://issues.apache.org/jira/browse/AMBARI-20540
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
    Affects Versions: 2.5.1
            Reporter: Attila Magyar
            Assignee: Attila Magyar
             Fix For: 2.5.1


Referenced Kerberos identity definitions should be created and distributed only if the referenced service or component is installed.
For example, if a service or component declares a referenced Kerberos identity definition like
{
  "name": "/HDFS/NAMENODE/hdfs"
},
The referenced identity, "/HDFS/NAMENODE/hdfs", should only be included related to principal and keytab file creation if the HDFS service and the NAMENODE component is installed in the cluster.
If the reference was
{
  "name": "/SERVICE1/service1_identitiy"
},
Then the referenced identity should only be included related to principal and keytab file creation if the SERVICE1 service is installed in the cluster.
