<p>I'm running Kafka in a Kubernetes environment. 
I want to adjust kafka log level to <code>WARN</code>.  I have a yaml file which I used with <code>helm install</code>.
In that yaml, there is a <code>envOverrides</code> parameter. Can I just add the following? And then <code>kubectl apply</code>? </p>

<p>Before: </p>

<pre><code>envOverrides: {}

</code></pre>

<p>After: </p>

<pre><code># Do I need { } ? 
envOverrides:
  kafka.log4j.root.loglevel: WARN
  kafka.log4j.loggers: "kafka.controller=WARN,kafka.producer.async.DefaultEventHandler=WARN,state.change.logger=WARN"
</code></pre>

<p>The environment variables are <code>KAFKA_LOG4J_ROOT_LOGLEVEL</code> and <code>KAFKA_LOG4J_LOGGERS</code></p>
