Hi Adamos, We will need some more info to figure out whats going on?
For the latest config update that you did, can you let me know if * the config type/tag is persisted > * exists in the "clusterconfig" table or, > * through API - > api/v1/clusters/mycluster/configuration?type=your_custom_service_type&tag=your > _new_version * the tag is selected at cluster level > * row exists with "selected" being 1 for that type and tag > * through API - api/v1/clusters/mycluster and check under the property > "desired_config" * there exists any entry for that type/tag in table "serviceconfigmapping" > * existence of entries here indicates one reason for the issue (let me know if > this is the issue and we can discuss a fix essentially mimic the action of > "ambari-server upgrade") The other possibility is that Starting the service does not create any command to re-install the client. To confirm this, can you analyze/share the ambari-server and agent logs when you issue the "Start" command. -Sumit From: ADAMOS LOIZOU <[email protected]> Reply-To: <[email protected]> Date: Friday, October 4, 2013 3:49 AM To: "[email protected]" <[email protected]> Subject: Reconfiguring services with client only components Hello, We use a custom service in our Ambari instance that comprises only of client components (i.e. no daemons). We used to control its reconfiguration by: 1. Stopping the service by changing the service state to INSTALLED 2. Changing the cluster configuration with a PUT in e.g. http://localhost:8080/api/v1/clusters/myclusterwith the following body: { "Clusters": { "desired_configs": { "type": "your_custom_service_type", "tag": "your_new_version", "properties": { }# properties here } } } 3. "Starting" the service by changed the state to STARTED. Even though the service would always remain in INSTALLED state (as being with client-only components) it had the effect of applying the changed configuration. We've recently synced our Ambari version with the latest from trunk and we no longer see that behaviour (the configuration is not applied). What would the correct way be of reconfiguring a service with client only components? Thank you Kind Regards Adamos Este mensaje se dirige exclusivamente a su destinatario.
