METRON-1348 Metron Service Checks Use Wrong Hostname
The Metron service check can often use the incorrect hostname when checking
the Alerts UI, Management UI, and REST services. This results in a failed
service check, even when the services are running successfully.
Ambari can run the service check on any node in the cluster, not just the
node the service is actually running on. The service check code currently uses
the hostname on which the service check is running. If the service is not
actually installed on that host, the service check will incorrectly fail.
The service check code was updated to find the hostname where the service
is installed and use that hostname.
## Testing
This change was tested by deploying Metron on Full Dev and running Metron >
Service Check in Ambari. The service check should complete successfully when
the cluster is healthy. The fix has also been tested on a multi-node cluster
in the same manner.
