@Michael Bronson Perhaps you can use services rest api to check like this:

curl -iv -u admin -X GET http://AMBARI_HOST:8080/api/v1/clusters/CLUSTER_NAME/services/KAFKA

If service is not installed you will received a response indicating resource does not exist.

@Michael Bronson For the password you need to send the basic authorization header like this

-H 'Authorization: Basic XXXXXXX'
