In ambari-server.log, I saw this:
04 Jun 2015 12:29:16,859 ERROR [qtp-ambari-agent-9668] StackVersionListener:82 – Unable to propagate version for ServiceHostComponent on component: NAMENODE, host: bi-hdp-secondary-18. Error: Stack data, stackName=HDP, stackVersion=2.2, serviceName=NAGIOS
This is probably the reason. NAGIOS suppose to be removed during Ambari upgrade and it is not in the list of Services in Ambari Web UI. What does this error mean. Why it refers NAGIOS?
