Elasticsearch (Java) disable logging

Question

I am trying to run a local Elasticsearch instance from within Java, but it's spamming my console with all sorts of messages. This is my code to build the settings and create the node:

Settings settings = ImmutableSettings.settingsBuilder()
            .put("cluster.name", "localcluster")
            //Paths
            .put("path.data", "ESConsole/data")
            .put("path.logs", "ESConsole/logs")
            .put("path.work", "ESConsole/work")
            .put("path.plugins", "ESConsole/plugins")
            .put("path.conf", "ESConsole/config")
            //Make the node unreachable from the outside
            .put("discovery.zen.ping.multicast.enabled", false)
            .put("node.local", true)
            .put("http.enabled", false)
            .build();
this.node = NodeBuilder.nodeBuilder().settings(settings).node();

I have tried creating a logger.yml and log4j.properties file and set the logging level to "ERROR" (as per this question), but that didn't seem to work (unless I did something really wrong). Is there a simple setting I can put in the settings builder (preferably) or do I have to create a settings file?

The reason I am asking this here is because all I could find was people that said something about a config file, while I would prefer to keep everything in code. If that's not possible, please let me know ;)

Thanks!

What I ended up doing is this:

    Settings settings = settingsBuilder()
            .put("http.enabled", false)
            .put("network.host", "127.0.0.1")
            .put("cluster.name", "my_cluster_name")
            .put("node.name", "my_node_name")
            .put("path.home", HOME.getAbsolutePath())
            .put("path.conf", CONFIG.getAbsolutePath())
            .put("path.logs", LOGS.getAbsolutePath())
            .build();

    // make sure ES' logging system knows where to find our custom logging.xml
    LogConfigurator.configure(settings);

    // startup a standalone node to use for tests
    return nodeBuilder()
            .settings(settings)
            .local(true)
            .loadConfigSettings(false)
            .node();

The key here is the LogConfigurator.configure() call. Note that I did have to copy a custom logging.yml file into the path.logs directory that simply disables the console logger.

I suspect if the settings included logger.level = OFF, then you wouldn't need a custom logging.yml file at all, but then you'd have zero logging (which might be what you want).
