Subject Re: Any way to reset Ambari Install Wizard?
Date Tue, 28 Jul 2015 19:48:20 GMT
try to restart ambari server and agents, then stop and start services,
sometimes services need to announce themselves to Ambari that they're
installed. Always refer to the ambari-server log. Worst case scenario,
delete Ambari_metrics service with API and clean up the postgres DB
manually, tables to concentrate on are hostservicedesiredstate,
servicedesiredstate etc. This should be last resort.
