CLOUDERA QUICKSTART 5.13如下所示

我不确定zookeeper out the box是否正在运行，如果是，那么它是否能够可靠地工作？我在尝试以独立模式从卡夫卡提供的下载版本中运行zookeeper时遇到了这个问题：

sudo jps在执行时显示QuorumPeerMain-我认为这是最近的zookeeper（？）：

当从cloudera安装启动zookeeper时，不确定如何使用它，如下所示。动物园管理员在工作吗？没有这样的杀戮过程意味着什么

基本上，我发现观察结果与标准描述不符。

因为您的错误表明您有

地址已在使用中

您应该弄清楚（如beny23所说）哪个进程占用该端口：

lsof -i :2181

运行zookeeper后，您应该会看到如下日志：

无论如何，您需要声明它（在zoo.cfg中）或在启动时将其作为变量传递。

您可以使用lsof-i:2181来确定哪个进程绑定到端口。当我运行该进程时，我会得到空输出。我总是习惯用纯香草的netstats来看看发生了什么。因此，我感到困惑。我会坚持下去。我的错误是，我期望一个简单的netstat显示2181端口上的zookeeper。事实并非如此。这个建议需要sudo在我的案例中先行，我现在可以看到zookeeper正在运行。谢谢
