我用的是apache spark的 spark-shell 使用mesos和zookeeper，似乎效果不错，只是我从zookeeper得到的日志比我想要的要多，这有点让人分心：

我试过换衣服 $SPARK_CONF_DIR/log4j.properties ```
log4j.logger.org.apache.zookeeper=WARN

这不起作用，但我并不惊讶，因为mesos文档提到zookeeper日志直接进入stderr：
注意：第三方日志消息（如zookeeper）仅写入stderr！
在spark的类路径中添加一个jar，这个jar有一个静态块，带有一个对zookeercapi函数的外部函数接口调用，以更改日志级别，这似乎是可行的，但我不确定，而且我没有任何从jvm调用c代码的经验。
