As per my understanding, CM performs canary tests for each of the enabled and active service in the cluster to ensure if those services are healthy.
However, I saw few errors last week related to Hive Metastore Canary test which failed because Hue was unable to create a test database in Hive Metastore. We do not use Hue actively and hence, it has been stopped. After I started Hue service the error was gone and everything reported healthy.
Did canary test actually happened on a stopped Hue service or there is something I might have missed? If CM still performs a canary test on stopped services, is there some mis configuration or CM is designed to do this?
