We are trying to implement alerting in our cluster and alerting is setup in Cloudera Manager.
So when I stop a service in Cloudera Manager, an alert is sent to my email.
Because for some reason I hear that if you stop the service from CM, it is not the same as it crashing on its own. Especially with regards Canary Alerts, which we will not get if we stop a service through Cloudera Manager.
So will I not get Canary Alerts for a service if the service is stopped through Cloudera Manager?
Also I would like to know how to stop a service manually through Cloudera API. I would appreciate it if some forum member could give the command to stop - say Oozie or HBase - through Cloudera Manager API.
