I see the alert as WARNING which should not create a problem. Is it possible to attach full log ?

Also what is the error while you issue ambari upgrade ? Please send logs also.

Here is the ambari-server log, just to say, the is not apptime server isntalled in this host.

@Roberto Sancho

Does this host lnxbigO4.cajarural.gcr exist at all? Could you please invoke the following URL and check for existence of this node and the services running on them:

http://:8080/api/v1/clusters//hosts>:8080/api/v1/clusters/<cluster_name>/hosts

Then drill down on this host to check the services installed.

If ATS is listed here, copy the URL, ensure that it really is not required and invoke an appropriate API to delete the service as listed in the Ambari Cwiki page

Is this a test cluster? if so, please obtain the following from ambari db:

select hostname from hosts;

select * from hostcomponentstate;

select * from hostcomponentdesiredstate;

Thanks & Rgds

Also, it is important to take a backup of the Ambari database before doing any API add/delete service operations.
