来自 Kafka Producer 的控制台消息过多

Question

如何控制 Kafka 生产者或消费者的控制台日志记录级别？我在 Scala 中使用 Kafka 0.9 API。

每次调用时send，KafkaProducer控制台都会给出如下输出。这是否表明我的设置不KafkaProducer正确，而不仅仅是日志记录过多的问题？

17:52:21.236 [pool-10-thread-7] INFO  o.a.k.c.producer.ProducerConfig - ProducerConfig values: 
compression.type = none
metric.reporters = []
metadata.max.age.ms = 300000
.
.
.

Kafka 服务器和 Zookeeper 查看的文件中有日志记录配置properties，但我假设这些配置不会影响 Kafka 客户端。更改这些文件中的一些日志配置，并重新启动 Kafka 服务器和 Zookeeper 以便重新加载这些文件，并没有解决问题。

谢谢

正确配置 logback 解决了我的问题： http://www.mkyong.com/logging/logback-xml-example/
