Question

我安装了新鲜的动物园管理员＆amp;卡夫卡。我开始他们两个。然后当我想用这个命令看到主题列表时：

bin/kafka-topics.sh --list --zookeeper localhost 2181

它让套接字连接关闭。这是屏幕截图：

    darpanshah@darpan-ubuntu:/opt/Kafka$ bin/kafka-topics.sh --list --zookeeper localhost 2181

提前致谢。卡住了。

这不是错误。主题详细信息从Zookeeper获取。因此，客户端（由kafka-topics.sh调用）首先连接到Zookeeper，然后建立会话，获取数据，然后在结束时断开连接。这是从Zookeeper获取一些数据的任何客户端的预期行为。

INFO客户端/127.0.0.1:48452的已关闭套接字连接，其中包含sessionid 0x15698f5ac360001（org.apache.zookeeper.server.NIOServerCnxn）
