Plugin configuration

rwxr_xr_x · February 12, 2021, 4:03am

Hello,

I'm converting a plugin built for ES 2.1.1 to ES 7.10.

I'm running into a strange issue. I need to pass:

plugin-name.enable: true

If I add it to elasticsearch.yml file, the configuration is available in my plugin but I get:

java.lang.IllegalArgumentException: unknown setting [plugin-name.enable] please check that any required plugins are installed, or check the breaking changes documentation for removed settings

I tried to find more information about how to tell ES that these settings are for my plugin, but I can't find anything. I did confirm in plugin-descriptor.properties that name=plugin-name.

Does anybody have any recommendations on how to do this?

Thank you.

Your plugin needs to declare the expected settings.

See for example

github.com

elastic/elasticsearch/blob/4d9ebcaabcf74c14bf71dd20d26de5eb937f9425/plugins/discovery-gce/src/main/java/org/elasticsearch/plugin/discovery/gce/GceDiscoveryPlugin.java#L90


        return new GceSeedHostsProvider(settings, gceInstancesService.get(), transportService, networkService);
    });
}
@Override
public NetworkService.CustomNameResolver getCustomNameResolver(Settings settings) {
    logger.debug("Register _gce_, _gce:xxx network names");
    return new GceNameResolver(new GceMetadataService(settings));
}
@Override
public List<Setting<?>> getSettings() {
    List<Setting<?>> settings = new ArrayList<>(
        Arrays.asList(
            // Register GCE settings
            GceInstancesService.PROJECT_SETTING,
            GceInstancesService.ZONE_SETTING,
            GceSeedHostsProvider.TAGS_SETTING,
            GceInstancesService.REFRESH_SETTING,
            GceInstancesService.RETRY_SETTING,
            GceInstancesService.MAX_WAIT_SETTING)

Thank you. This is exactly what I was looking for. I confirmed that it resolves the issue.
