Actually, a mix of two solutions worked for me:
https://community.hortonworks.com/articles/60805/deploying-a-fresh-metron-cluster-using-ambari-serv....
and
https://github.com/apache/metron/tree/master/metron-deployment/packaging/ambari/metron-mpack
then navigate to Ambari web interface, and then go to "Admin -> Stack and Versions -> Versions tab -> Manage Versions -> Click your current HDP version"
Now it shows Kibana, Elasticsearch and Metron with "Add Service" links available.

Good luck!
