apache - Zookeeper 报错连接丢失异常

Question

我正在亚马逊 EC2 实例上运行 SeqWare VM 我正在​​尝试使用 SeqWare 查询引擎从 VCF 文件中查询数据。当我第一次启动实例并按照说明导入数据时，它工作正常，并继续工作直到我停止实例。当我重新启动它时。它不会让我导入任何东西，也不会创建新的工作区。它总是返回以下错误。我查看了这些进程，发现所需的节点都没有运行，所以我登录到 root 并转到 etc/init.d 目录并重新启动所有内容，此时，当 T 尝试导入数据，我什至没有收到错误，我必须停止该过程。

我明白了。apache 服务是从 cloudera 包中安装的。当实例重新启动时，它们并没有被重新启动，显然，只是从 etc/init.d 运行它们的脚本是不正确的方法。我在 cloudera 文档中找到了重启它们的命令。
