After conversation with Hortonworks developers working on LogSearch. Two conclusions: 1. For additional 3rd party services nothing enforce their restart in Ambari. It is not part of the 2.5.x current design. The Log Feeders should be restarted manually. 2. The integration of services in Ambari Log Search for 3.0 will be slightly different. Services wont include *-logsearch-conf.xml configuration file anymore. They should include file a called input.config-<service_name>.json.j2 at package/templates in their stack definition, instead. This template wont be editable as an Ambari property. The template will be handled by Ambari internally (post install hook) to create a json file which will be deployed to the Log Feeders for the first time. ... View more
