kafka启动不断刷屏

bin/kafka-server-start.sh config/server.properties 启动kafka时被下面两行日志刷频：
  INFO Creating /controller (is it secure? false) (kafka.utils.ZKCheckedEphemeral)
  INFO Result of znode creation is: OK (kafka.utils.ZKCheckedEphemeral)

把zookeeper的dataDir：/tmp/zookeeper文件夹删掉重启了zookeeper和kafka之后就正常了。
